Tests are crashing with corrupted stack.



================
Comment at: lib/sanitizer_common/sanitizer_linux.cc:800
+#else
+  return internal_syscall(SYSCALL(vfork));
+#endif
----------------
You can't return from a function that calls vfork() in the child process. It will destroy the stack frame in the parent process.
