Mea culpa. In trying to create a minimal reproduction case, I botched.
Here's a better case:
#include <ev.h>
#include <stdio.h>
void catchf(struct ev_loop* loop, ev_signal* w, int r) {
ev_unloop(ev_default_loop(0), EVUNLOOP_ALL);
printf("caught SEGV\n");
}
void laterf(struct ev_loop* loop, ev_periodic* p, int r) {
printf("triggering SEGV\n");
int* f = (int*)0x0;
*f = 9;
}
int main(int argc, char** argv) {
ev_signal catcher;
ev_periodic later;
ev_signal_init(&catcher, catchf, SIGSEGV);
ev_periodic_init(&later, laterf, 0, 3, NULL);
ev_signal_start(ev_default_loop(0), &catcher);
ev_periodic_start(ev_default_loop(0), &later);
ev_loop(ev_default_loop(0), 0);
printf("loop exited\n");
return 0;
}
