<pre>=== SOURCE ===
// checking for class std::bad_exception
#include <stdio.h>
#include <exception>
using namespace std;
void bad_exception ();
void foo () throw (std::bad_exception)
{
// throw an object of a disallowed type
throw 0;
}
void handler ()
{
// throw an object of a type not allowed by the exception-specification
// of the function that already violated its specification (due to which
// the handler has been called); this requires the exception object to be
// replaced by the runtime library by one of type [std]::bad_exception
throw "";
}
int main ()
{
std::set_unexpected (handler);
try {
// will fail if runtime library doesn't recognize std::bad_exception
// by calling terminate()

}

}
=== EXPECTED (LIBSTDC++) OUTPUT ===
return 0 - PASSED
=== REAL (LIBC++) OUTPUT ===
$ ./a.out
libc++abi.dylib: terminate called throwing an exception
Abort trap: 6
$ echo $?
134
=== COMPILER ===
$ clang --version
Apple LLVM version 4.2 (clang-425.0.24) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.0.0
Thread model: posix
=== ADDITIONAL ANALYSIS ===
This is library problem, because the Intel compiler's outputs are the same on
options -stdlib=libc++ and -stdlib=libstdc++.</pre>
