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;
}
