Signal handling appears to be broken. Here's a simple testcase. Run the program
and hit control-c. It'll print "got Alarm clock", then stop accepting any
signals at all, even SIGSTOP. The same program works fine on my Debian stable box.
#define _GNU_SOURCE 1
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <pthread.h>
int
main()
{
sigset_t waitmask;
int sig;
sigemptyset (&waitmask);
sigaddset (&waitmask, SIGINT);
sigprocmask (SIG_BLOCK, &waitmask, NULL);
for (;;) {
sig = sigwaitinfo (&waitmask, NULL);
fprintf (stderr, "got %s\n", sys_siglist[sig]);
if (sig == SIGINT) {
break;
}
}
return 0;
}
