I've read the chapter in the new FAQ that discusses the subject. It is
very insightful (thanks to Eli for that).
I have a situation where the first (or is it called last?) entry in
the traceback list shows the function which is not called from the
previous function at all. Which leads to a suggestion that the RAM in
that place was corrupted by another process. And the problem is that
the crash can't be easily reproduced.
The good idea would be to have a disassembly in the places indicated
by the last 2-3 tracebacks, maybe few commands before and after the
exact traceback location.
So the question is - does anyone know how to hook exception (SIGSEGV
or page fault) for the purpose of saving to a file the memory contents
from around the locations indicated by traceback list?
Any ideas appreciated.
