C++ does not catch exceptions when used with Haskell-main and linked by ghc

Consider the C++ program

// Main_cc.cc
#include <iostream>
#include <exception>
extern "C" {
int func() {
  try {
    throw std::runtime_error("THIS FAILS!");
  } catch(const std::runtime_error &c) {
    std::cerr << c.what();
  }
  return 0;
}
}

and the Haskell program

-- Main.hs
module Main where
import Foreign.C.Types
foreign import ccall func :: IO CInt
main :: IO ()
main = print =<< func

When compiled with

ghc --make Main.hs Main_cc.cc -lstdc++

and being run on mac os x 10.11.3 the result is

libc++abi.dylib: terminating with uncaught exception of type std::runtime_error: THIS FAILS!
Abort trap: 6

and not (as it should be):

THIS FAILS!0

When compiled in a similar way under windows some c++ exceptions of a larger project are not caught as well. However, these were hard to track down and I was unable to construct a simple example like the one above.

As a workaround one can

• write a main() function in c++ and call from there into Haskell,
• compile the Haskell-Module with the options "-c -no-hs-main", and
• link the application using g++ (not ghc!).

When being compiled / linked this way, all c++ exceptions are being caught in mac os x as well as under windows.
