(Corrected message after hint of Angus Leeming)
I have the following problem:
Sometimes LyX (cvs, xforms 1.0RC4) chrashes with collapsing X-Window after
generating of the ppm files for the preview.
This problem does not depend of the number of formulas (also for about 300
formulas). Sometimes the text can be read, some minor changes lead to
chrashes, some addititional minor changes allow to read the text again with
preview.
So I had a text, which chrashed. I opened the text with LyX (qt3), added a
formula, saved the text with new name. Then I deleted the formula with an
editor. The new text could then be read with LyX (xforms) and preview
works. The onyl difference of the tow files were some additional empty
spaces.
However, it does not work every time.
Angus Leeming asked me for a backtrace. The question is, how to make it:
If I run
gdb lyx-cvs1.3.0
then I cannot enter bt, because X-Window is collapsing.
I tried to start X-Window in the debugger,
gdb xdm, gdb kdm, gdb xinit
but X-Window stops (the window manager is not startet).
Then I changed the ulimit value. So LyX generates now a core file, if LyX
chrashes alone. With gdb -c core and then bt I could make the
backtrace.
But if X-Window collapses too, as described above, I don't get a core file.
Does somebody has an idea to make the backtrace?
