Hello,
I'm trying to debug a segment violation, I compiled the program with -g,
but analyzing the core dump isn't really helpful, maybe the "warning
can't read pathname for load map" is the cause? Or it's possible that
it's caused by some of the c libraries used having no debug symbols? Any
hint?
Here's my gdb session:
$ gdb ./botphone core.28682
Try the following:
gdb -c botphone core.28682
inside gdb you can do things such as back-trace.
