Well largely, ALL I want is the backtrace -- and I'm wondering if I could cobble something together that could get it. The problem is it needs to look at the symbol table, and I dont know how to get at that via C -- ie, gdb doesnt have an interface that I know of that you can link in to grab a stack trace and exit.
Its been a while since I prowled the gdb source. I may not be able to do anything automatic like you want -- but I sure wish that tool was available!
Maybe we could script it. If we can convince python, in the event of a SIG11, freeze every other thread and run some python function, or even an external script, we could make this script invoke gdb with another script (a gdb script) that would attach to the zope python process and get a stack trace of every thread. No need to get fancy with C. Now the nice thing would be if I could generate a Zope package just like the binary Zopes at zope.org, but compiled with my options (such as -g). Speaking of options, is linux-binary-Zope-2.4.3-python still being compiled with --pymalloc? As I mentioned before, our segfaults reduced drastically WITHOUT it.
