SIGSEGV

I am getting segmentation fault at:  

signal SIGSEGV, Segmentation fault.
0x00007f21293df7c3 in __kmp_cleanup_threadprivate_caches () at ../../src/kmp_threadprivate.cpp:812

Since, I can't provide code details. Could you please suggest something which could be the possible reason behind this?

My cases run fine in optimize version, but with debug, If I use gdb, I get this following error at the exit of executable.

..._cleanup_... suggest the error is occurring at thread termination. Can you ascertain as to if the thread termination is expected at that point of execution .OR. is an abnormal termination?

IIF at the expected point of termination (in Debug mode), then check to see if you have specified sufficient stack size. Note, stack size for main thread and additional threads are not (necessarily) the same. Consider experimenting with environment variable KMP_STACKSIZE or kmp_set_stacksize_s() (called prior to 1st parallel region).

OR IF unexpected termination of thread, then you have an error elsewhere in your program that is (appears to be) benign in release mode. Have your built Debug mode with full runtime checks?
