After reducing the testcase a lot, I ended up with
{{{
#include <iostream>
#include <pthread.h>
#include <stdlib.h>
#include <unistd.h>
pthread_cond_t ptcond;
pthread_mutex_t *ptmux;
void* fun(void*)
{
pthread_mutex_lock(ptmux);
while (true)
pthread_cond_wait(&ptcond,ptmux);
for(;;) sleep(1000);
}
int
main(int argc, char *argv[])
{
pthread_mutex_t ptm;
pthread_mutex_init(&ptm,__null);
pthread_cond_init(&ptcond,__null);
ptmux = &ptm;
pthread_t pt;
pthread_create(&pt, 0, fun, 0);
for(;;) sleep(100);
}
}}}
The main thread for this process is unkillable. Interestingly, sending
SIGTERM, SIGINT or SIGKILL to the other thread kills the process.
