regression 1010: Clang: prevent unwanted optimization Calling a NULL function pointer is undefined behavior in C, therefore when the compiler identifies such a pattern it is allowed to do pretty much anything. Clang simply does not take the "case 3" branch in ta_entry_bad_mem_access(). In order to force the call, this patch uses a volatile function pointer so that the compiler cannot assume anything about its value.
