为什么OSX上的异常不能与gcc7和-static-libgcc一起使用？

Question

If I compile this simple program with gcc-7, -static-libstdc++ , and -static-libgcc ; then run on OSX

#include <exception>
#include <iostream>

int main() try {
  throw std::runtime_error{"abc123"};
  return 0;
} catch (const std::runtime_error& e) {
  std::cout << e.what() << "\n";
  return 0;
}

it fails with error code 134.

Why doesn't it print "abc123" as it does when compiled with the same options on linux?

Fixed(-ish) in GCC8; see update to PR86215 and the related PR80556 .
