@maroszek thanks for the check, a patch is now commited. I'm setting the status onto feedback
as you have yet more issues.
Unfortunately I've no Mac to test it. But how it sounds like, the crash and the timeout issues
are two separate things. As from your code, the requests should not be hanging but just running
through, so no timeouts are expected. Though, as you've already said, Mac will use another
threading library, so maybe it could condition the issue, but just a guess. You probably should
debug through and check which request are not running through and why. Maybe there's a way to
reproduce this on Linux as well.
So set this to feedback, but i'd rather suggest to indeed close this one and to open another
ticket for the exact timeout issue you experience. Please feel free to do so if you think it's
ok.
Thanks.

It seems to fix the segfault for Debian :)
But unfortunately this does not fix the problem on OS X.
If you look at the error message:
<b>Fatal error</b>: Maximum execution time of 30 seconds exceeded in
<b>Unknown</b> on line <b>0</b><br />
This does seems more like a timing/signaling bug, doesn't it? The timeout should never be
hit...
Do you have any chance to test this issue on OS X? Can i be of any further assistance?

Thanks for the update. Yeah, now it works. Please check whether this fixes the issue on your side

It namely didn't crash on my side, but after some debugging valgrind showed issues. This seems
pretty matching with the recent bug #71115.
Thanks.

Hi! Thanks for verifying! For Debian you need to change it a bit.
This should work:
g++ crash.cpp -Imain -ITSRM -IZend -I. --std=c++11 -Llibs -lphp7 -lxml2 -lresolv -ldl -pthread
