Status: Open
Bug Type: MySQL related
Operating System: Solaris 8
PHP Version: 4.1.1
New Comment:
I'am having the same problem using apache2 and latest cvs.
I see that ext/mysql/libmysql/
is always compiled with #define UNDEF_THREADS_HACK
so producing a non thread safe mysql builtin library.
Not using the builtin libmysql this problem is solved.
Don't know if it's the same for win32 builds.
I also noticed that build this libmysql the debug code
is not turned off definig DBUG_OFF (?), is this intented ?

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:
