I've got problems running libev in complex environment under FreeBSD.
with gcc (GCC) 4.2.1 20070719 [FreeBSD]
I've got core dump and tracked problem to next piece of code in
ev_poll.c(poll_poll):
...
else
for (p = polls; res; ++p)
if (expect_false (p->revents)) /* this expect is debatable */
{
--res;
if (expect_false (p->revents & POLLNVAL))
fd_kill (EV_A_ p->fd);
..
}
...
at the for time `polls' looks like this:
{fd = 3, events = 1, revents = 0}
{fd = 6, events = 5, revents = 4}
{fd = 775043377, events = 13873, revents = 11832} (**)
...
i don't know `res' value, but i suppose it was 2.
of course this situation is incorrect for the code above, because `p'
will eventually point to (**) uninitialized record (but present in
memory).
So, i think `res' must decrease in conjunction with `p' increasement,
like this:
...
else
for (p = polls; res--; ++p)
if (expect_false (p->revents)) /* this expect is debatable */
{
if (expect_false (p->revents & POLLNVAL))
fd_kill (EV_A_ p->fd);
...
what do you think?
thanks
PS: i dont get any problem running current libev implementation under
linux and in most situations under freebsd
