I'm trying to debug an emacs crash and am having trouble getting a useful backtrace after the crash. Here's an example:
#0  0x00289c08 in ?? ()
No symbol table info available.
#1  0x007ba148 in _malloc_mutex ()
No symbol table info available.
#2  0x00000000 in ?? ()
No symbol table info available.
Aside from the lack of information, the most salient feature of this is 
that _malloc_mutex is actually a variable, not a function, so the 
information for frame #1 makes no sense.
I'm not very experienced at debugging, but I'm wondering if I can get 
anything out of this sort of backtrace.  Or does it just indicate that 
the stack got corrupted?
Thanks in advance for any suggestions.

Ken
