Segfault at the fery first line of __kmp_dephash_free_entries() while trying to dereference a pointer passed as a parameter. The pointer to memory allocated by __kmp_fast_allocate() became invalid after __kmp_free_fast_memory() was called.
Comment at: runtime/src/kmp_runtime.c:5704
__kmp_free_fast_memory( thread );
#endif /* USE_FAST_MEMORY */
See comment below (line 5757)

__kmp_reap_team( thread->th.th_serial_team );
Calling this after __kmp_free_fast_memory( thread ); was called in line 5704 causes crash on sparselu_taskdep benchmark from kastors suite.
