...ative, in which each setjmp tags the jmpbuf to show which flavor of longjmp is required. Below is the header file that I defined to wrap the setjmp/longjmp calls. ZZ_SIGSETJMP augments the jmpbuf with a function pointer to a longjmp call that is compiled in the same compilation unit as the setjmp. ZZ_SIGLONGJMP calls through this function pointer. This way, an llvm-compiled longjmp is used for every longjmp to an llvm-compiled setjmp; and a gcc-compiled longjmp is used for every longmp to a gcc-compiled setjmp. C++ exceptions or destructors wouldn't be handled properly, but that doesn't matter i...
