Re: [mpls-linux-general] gdb out put of segmentation fault.

Perhaps the problem here is some pointer which is not valid in current
context is tried to be freed. I dont know the ready made solution, but
look for a "free" statement that u think should get executed before the
malloc where the core dump is occring. Or you could be freeing more data
than malloced in previous case.
