PHP :: Bug #37438 :: PDO_MySQL segfaults Apache child

[2006-05-14 16:15 UTC] indeyets at gmail dot com

Description:
------------
After upgrading from 5.1.2 to 5.1.4 apache childs began to segfault at some requests. Backtrace showed, that the problem lies inside of PDO_MySQL.

The issue was originally mentioned here: http://pecl.php.net/bugs/bug.php?id=7433

reverting this patch solves the issue: http://cvs.php.net/viewcvs.cgi/php-src/ext/pdo_mysql/mysql_statement.c?r1=1.48.2.12&r2=1.48.2.13

Actual result:
--------------
#0  0x2908180a in mysql_more_results () from
/usr/local/lib/mysql/libmysqlclient.so.15
#1  0x29064c4c in pdo_mysql_stmt_dtor (stmt=0x8743124) at

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

This appears to be a bug related to the Primary Key. I experienced the issue with a table that had an integer primary key (non auto inc) and PHP would segfault if the table had a row who's PK == 0. Deleting the row solved the problem

Bug still exists in 5.1.6
