[boost] error_handling_test hungs

Hi,

I have some problem with gcc that came with cygwin. I remember it was
reported before either. error_handling_test hangs during run. Here what I
was able to minimize it to:

#include <signal.h>
#include <setjmp.h>
static sigjmp_buf& jump_buffer()
{
    static sigjmp_buf s_sigjmp_buf;
    return s_sigjmp_buf;
}
extern "C" {
static void execution_monitor_signal_handler( int sig ) {
    siglongjmp( jump_buffer(), sig );
}
}

int main()
{
    struct sigaction action_for_all_signals;
    action_for_all_signals.sa_flags = 0;
    action_for_all_signals.sa_handler = &execution_monitor_signal_handler;
    sigemptyset( &action_for_all_signals.sa_mask );

    sigaction( SIGFPE , &action_for_all_signals, NULL );
    sigaction( SIGSEGV, &action_for_all_signals, NULL );
    sigaction( SIGABRT, &action_for_all_signals, NULL );

    volatile int sigtype = sigsetjmp( jump_buffer(), 1 );
    if( sigtype == 0 ) {
        int a = 0;
        a = 1 / a;
    }
    else {
        throw 1;
    }

    return 0;
}

This code snippet hangs. Any leads? Note how it's behavior differ depending
on which sigaction statement you comment.
