Hi guys,
Today I am debugging an issue related to memory leak.
I use gdb 7.7 and python 2.7.6 to generate one core dump file from production env.
And then, just use gdb to debug the coredump upon the same machine.
Got error that seems not support debug core file using pyton?
Here is snippet:
[root@localhost server]# gdb --core memleak.core
