PHP Bug Type: MySQL related
Bug description: PHP segfault in mysql driver
Running PHP under continuity (pthread based), and serving
phpMyAdmin 2.2.2, connecting remotely to a 3.23.47 mysql
database.
The server randomly crashes(trace below), but not always.
The seg fault doesn't seem to be related to load, length of
server operation, etc. It can crash on the 1st or 80th load
of a phpMyAdmin page, but is fairly reproducable. If the
server is restarted, may operate normally right away or it
may not.
Backtrace:
