Hi,
I'd created a ticket for this a few days ago but I should have emailed this
list first.
http://www.lyx.org/trac/ticket/6564
Since filing this report I have discovered a little more and hence the issue
title is more restricted than the bug itself. Basically, when using the left
arrow key to back out of an inline math formula inset that is by itself in a
table cell, I get a crash.
Also, in an eqnarray, I get this crash when backing out of a cases env. in
some cell. Looks like there is an issue when nesting table-like env.
My GDB backtrace shows that this error happens at the same location in
InsetMathGrid::getStatus() (InsetMathGrid.cpp:1424) code path in either of
the above cases is different (obviously). It seems to be due to an
out-of-bounds access on a column-info container.
Platform: KUbuntu 8.04 / i686
