Thanks for taking a look at this. Agreed it will be difficult. After this session I will rebuild Emacs with CFLAGS="-O0 -g" and run with GDB attached to try to get a higher quality trace. (The recipe to reproduce the crashes I've been seeing may be hard to obtain. I haven't identified any particular activity that triggers these crashes, and maybe there are different causes each time -- this is just the first one I captured.) > Still, I ask you below to produce some values from GDB in the hope > that this would give some ideas.

Hi,
I have been having long-running Emacs sessions crash, rarely, and I
finally caught one case in GDB. Full backtraces attached. I don't know
how it->string becomes 0x0, but it looks like SCHARS (it->string) then
attempts to dereference the null pointer. I'll keep the session running
in case there is anything else someone wants me to check.
Thomas
