http://bugzilla.lyx.org/show_bug.cgi?id=4055
The attached patch (4055.diff) fixes one part of this crash. However, LyX
still asserts when "rtl support" is checked in Preferences->Languages (i.e.
in the default settings). I suspect the bidi tables are not correctly
updated, but I don't understand the bidi thing, so someone else will need to
have a look.
If we don't find an easy fix for the bidi issue, 4055-alt.diff has an
alternative fix that cures the crash, but isn't really the behaviour the user
would expect (the selection is reset, not replaced by the math symbol).
Better than a crash, though.
Testcase (with 4055.diff applied):
- C-N
- type "test"
- select this word
- M-x math-insert \alpha
Assertion triggered in const lyx::Font lyx::Paragraph::getFontSettings(const
lyx::BufferParams&, lyx::pos_type) const by failing check "pos <= size()" in
file Paragraph.cpp:1317

Save seems successful. Phew.
