std::cerr on linux with clang++ and libc++ causes SIGABRT

问题

I'm trying to get a simple program running on Ubuntu 12.04 x64 compiled with clang++ 3.3 libc++ libc++abi .

Program:

#include <iostream>
int main(int argc, char **argv) {
  try {
    std::cerr << "Test cerr \n";
  } catch (...) {
    std::cout << "catch exception";
  }
  return 0;
}

Writing to std::cerr prints the message, but results in SIGABRT.

However, writing to std::cout works fine.

Here the ldd output of the executable:

$ldd cerr_test
linux-vdso.so.1 =>  (0x00007fffce5ff000)
libc++abi.so.1 => /usr/local/lib/libc++abi.so.1 (0x00007fa4079fd000)

/lib64/ld-linux-x86-64.so.2 (0x00007fa407c55000)

Can anyone give me a hint how to fix this?

Here is the backtrace:

It works finally by using libcxxrt instead libc++abi as suggested by @chico
