D:\src\llvm-ninja-rel64>type jmp_set.cc
#include <setjmp.h>

int main() {
  jmp_buf buf;
  if (setjmp(buf))
      return 4;

  longjmp(buf, 1);
}

D:\src\llvm-ninja-rel64>bin\clang-cl -m64 jmp_set.cc /MD
D:\src\llvm-ninja-rel64>jmp_set

Crashes:
>	ntdll.dll!string "Enabling heap debug options\n"()	Unknown
     kernel32.dll!RtlUnwindExStub()    Unknown
     msvcr120.dll!longjmp()    Unknown

Works fine either without /MD or in -m32 mode.
