Okay, it seems it was my fault, I was being clumsy, Anyway, I suspect that
sometimes the process somehow ended.
GDB was stuck, so as you said, I pressed CTRL+C and did a backtrace:
```gdb

I've been researching a bit, it seems this function waits for changes in open
files, the source code compatible with the backtrace is:
```c
int
__poll (struct pollfd *fds, nfds_t nfds, int timeout)
{
#ifdef __NR_poll
return SYSCALL_CANCEL (poll, fds, nfds, timeout);
#else
struct timespec timeout_ts;
struct timespec *timeout_ts_p = NULL;
if (timeout >= 0)
{
timeout_ts.tv_sec = timeout / 1000;
timeout_ts.tv_nsec = (timeout % 1000) * 1000000;
timeout_ts_p = &timeout_ts;
}
return SYSCALL_CANCEL (ppoll, fds, nfds, timeout_ts_p, NULL, 0);
#endif
}
```
I haven't been able to find out where `_NR_poll` is defined, though it seems it
has to do with certain types of kernels.
So, I'd say that Geany wants to check if any open file has changed and is
waiting for `poll()` to return, but for some reason this never happens.
