libstdc++-v3 configure hangs again. An old problem with signals.
This is a  piece of code which hangs and  a strace log.

#include <unistd.h>
#include <signal.h>
#include <setjmp.h>

static jmp_buf	env;
int signo = SIGSEGV;

static void sig_handler(int sig)
{
    static sigset_t x;
    signal (sig, sig_handler);
    sigemptyset (&x);
    sigprocmask(SIG_SETMASK, &x, NULL);

    longjmp(env, 1);
}

int main(int argc, char * * argv)
{
    if (setjmp(env) == 0 ) 
    {
        signal(signo, sig_handler);
        *(char*)0 = 1;
    }
    return 0;
}
