PHP Bug Type:     Reproducible crash
Bug description:  mysqli can't handle a reconnect, crashes

Description:
------------
If you set mysql timeouts (in my.cnf) to some short times, like:
set-variable = connect_timeout=3
set-variable = interactive_timeout=5
set-variable = wait_timeout=10

And then have a script, that opens mysql connection via mysqli, sleeps for
20 seconds and then tries to do something with that connection, php
crashes.

Reproduce code:
---------------
Simple enough to reproduce from the comment above

Actual result:
--------------
Segfault:
