oneTBB: Crash when statically linking TBB 2018_U3 on OS X

Statically linking with gcc on OS X can cause TBB to segfault.

This simple program segfaults when TBB is built with GCC 7.3 and linked in statically.

#include <tbb/task_scheduler_init.h>
#include <iostream>
#include <cstdlib>
#include "a.pb.h"

using namespace tbb;

int main(int argc, char* argv[]) {
  A a;
  tbb::task_scheduler_init tbb_init{};
  std::cout << a.DebugString() << "\n";
  return 0;
}

Note: that it works if protobuf isn’t linked in.

I posted here and included the coredump, exectuable, and a bazel build that can reproduce the issue.

This is the backtrace from the crash:
