[Freeswitch-users] recompile with gdb

Tue Sep 22 12:04:25 PDT 2009

Hi,

Nope, I'm still on Debian 5.0... in transit to CentOS 5.3 but it needs to
wait a bit.
i was talking about gdb, not gcc and was trying to recompile FS with debug
symbols on: CFLAGS="-g -ggdb" MOD_CFLAGS="-g -ggdb".

yes, I understand that gcc segfault most probably means only one thing... HW
isues. This is sometihng that I'm going to check tomorrow.... running
memtest to see what i get. Also, I will repeat the same test with a new
block of RAM.

Maybe i didn't explain myself well... apologize.

T.
