[Freeswitch-dev] QUESTION: Additional info on a core dump?

[Michael Collins]

FYI,

I have a non-reproducible core dump and I noticed I get output I'd not
seen before. I was just curious if some extra goodies had been added
to tree? I noticed that it said "*** glibc detected ***" and I don't
recall seeing that previously. Anyway, I was just curious. This
particular segfault happened during shutdown after I'd made about 1300
openzap calls and 22 of 23 PRI B chans were stuck in HANGUP or
TERMINATING mode. (See OPENZAP-9)

Is this extra output normal and should we expect to see it going
forward if we have seg faults? I want to make sure I tell people what
to include in bug reports, pastebins, etc.

Thanks,
MC
