wireshark 1.12.8 core dump trace

Hi, We have some issue when executing wireshark 1.12.8 in RHEL santiago. The wireshark core dumped and after gdb, bt command with that core dump, the below o/p is get

#0  0x00007fdc5f57a782 in ?? ()
#1  0x00007fdc603b2fc0 in ?? ()
#2  0x00007fdc60188c46 in ?? ()
#3  0x00007fdc54bac070 in ?? ()
#4  0x0000000000000000 in ?? ()

so we are not getting any function or file which is causing dump. we are modified many files of wireshark according to compliant with proprietary messages and IEs, we have make files which run fine for same changes on wireshark 1.10.6 version.

My question is more on GDB than Wireshark related. Please let me know how to trace the memory stack mentioned before.
