The assignment name = sub.str(1) reads from the first argument given to
regex_match(), but previously this was a temporary object which was already
out of scope. This did probably not matter much in practice, but invoked
undefined behaviour, and as we all know this is allowed ton format your hard
disk or kill to your cat, so better fix this.
This is different from bug #8999, since in this case a new macro instance is
created. You still get a TeX capacity exceeded error if you try to typeset the
exported document, but this is the same as for bug #8999 and better than a
crash.
Thanks to maciejr we know now what the remaining problem was with bug 7954:
My unicode symbol fallback works fine, the problem was that a font named
"Symbol" is available on OS X, but it does not use the font-specific encoding
we expect: Almost all glyphs are at their unicode code point.
Therefore the bug is fixed by re-enabling the unicode workaround and blocking
the Symbol font on OS X.
BufferParams::setDocumentClass() deletes the old document class of the buffer
and creates a copy of the new one. Therefore, the stored layout pointers in
the paragraphs (actually only one paragraph exists) are dangling afterwards.
Resetting them before setting the document class helps here.
In the long term we need to get rid of BufferParams::setDocumentClass()
completely, this is very ugly.
Invoking a computer algebra system program for computing a selected
subformula has never worked (checked with all LyX versions back to 1.3)
and, moreover, in the presence of a selection things go awry.
This commit allows this computation by replacing the selected
subformula with the result of the computation.
much easier to find what you need, especially when we're trying
to help users. Previously, they were sorted by their enum values.

mhchem loads amsmath and needs therefore be loaded after it but before packages that redefine commands of amsmath. We already take care of esint but not of wasysym
The check for a latex format is very fragile. Both libmagic and our
guessing from contents cannot distinguish the pstex and pdftex formats
used by the xfig external inset. Moreover, it may also happen that
lyx files are mistaken as latex ones. Thus, when the guessed format
is latex, the only solution is to give precedence to the format
determined by the file extension.
Multirow cells now have the same alignment rendering in LyX
as in the output. The alignment of a multirow can change as
long as the column is not of fixed width. If the column is
of fixed width, the multirow is left-aligned.
When setting a multirow, the alignment is copied from
the last cell in the selection.
The command line argument -geometry WIDTHxHEIGHT±XOFF±YOFF
specifies a preferred size and location for the main window.
Currently, this is semi-broken on Windows. Indeed, only
specifying WIDTH and HEIGHT places the main window such that
the left and top borders are invisible such that the window cannot
be moved. Moreover, the XOFF and YOFF parts (when present) are
used to specify the distance of the window from the left and top
or right and bottom edges of the screen, when using '+' or '-',
respectively. However, -geometry 800x600-20-20, instead of placing
the window such that its bottom and right edges are at a distance
of 20 pixels from the corresponding screen edges, places the
window such that its left and top borders are out of the screen.
This is corrected by this commit.
Investigation of bug #9236 showed that crash to be due to a Paragraph's
holding a dangling pointer to an old and deleted Layout after the
DocumentClass was reset. Since the backtraces look almost identical, it
seems likely that we have the same problem here.
Since this crash seems almost always to involve tables, I looked at the
code in switchBetweenClasses() and found that the Paragraphs that belong
to "hidden" table cells are not seen by the initial recursion using a
ParIterator: It skips right over them. This was confirmed by test code
suggested by Enrico, with results reported in Trac.
The present patch attempts to deal with this problem in the second
recursion, over Insets. When we see an InsetTabular, we call a new
routine that recurses through the cells, looking for hidden ones. If it
finds a hidden one, it then resets the Layout for the cell's Paragraphs
(there should be only one, but we do not make any assumptions) to the
PlainLayout that belongs to the new DocumentClass. This is good enough,
since such cells never have content.
There is extensive discussion of the patch here:
https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg185095.html
Additional testing by Enrico and me confirmed the existence of the
dangling pointer.

If LyX does not know about a given file format, it may easily
happen that the format is recognized as "latex" and this causes
bug #9146. This patch limits the check for a latex format to
non-binary files. The strategy for deciding that a file has
binary content is the same as that adopted by the "less" program.
This is a stripped down backport of the more complex fix in master.
For Windows: AcroRd32, SumatraPDF and gsview (both 32 and 64 bit versions).
For Unix: qpdfview.
Qpdfview is a nice alternative to Okular for KDE users and a superior
alternative to Evince for Gnome users, due to its complete synctex
support. It only depends on Qt libraries for the graphical interface.
Forthcoming versions of cygwin will use a different mechanism for
obtaining passwd/group information based on /etc/nsswitch.conf.
Thus, it will not be guaranteed that the files /etc/passwd and
/etc/group even exist. The recommended way for obtaining those
info is by using the getent command, which already works in
current versions.
If the reverse position corresponds to an inset, its paragraph id
does not follow the main text numbering. Typically, an inset has
only a few paragraphs, so that we would jump near the beginning of
the document. Now the cursor in LyX jumps to the right spot.
