[Bug 418220] Re: apache2 crashed with SIGSEGV in pdo_parse_params()

[DarkNova]

I have been analyzing the differences between my Jaunty server which has
the segmentation fault problem, and a Jaunty virtual machine which works
fine. I've determined the key difference:

The problem machine has package php5-mysql (version
5.2.6.dfsg.1-3ubuntu4.2) installed. To eliminate the segmentation fault,
I installed a different (apparently older) version of pdo and pdo_mysql
by doing "sudo pecl install pdo_mysql" which overwrote Ubuntu's
installed pdo and pdo_mysql libraries.

These modified libraries are found at /usr/lib/php5/20060613/pdo.so and
/usr/lib/php5/20060613/pdo_mysql.so.

Key file version differences:

pdo.c: BAD: 1.57.2.17.2.10.........GOOD: 1.57.2.17
pdo_dbh.c: BAD: 1.82.2.31.2.22.........GOOD: 1.82.2.30
pdo_sql_parser.c: BAD: 1.35.2.6.2.15 ...........GOOD: 1.35.2.6
pdo_sql_parser.re: BAD: 1.28.2.4.2.12...........GOOD: 1.28.2.4
pdo_sqlstate.c: BAD: 1.7.2.1.2.2..............GOOD: 1.7.2.1
pdo_stmt.c: BAD: 1.118.2.38.2.34............GOOD: 1.118.2.38
php_pdo_driver.h: BAD: 1.66.2.11.2.8...........GOOD: 1.66.2.11
php_pdo.h: BAD: 1.7.2.5.2.4...............GOOD: 1.7.2.5

mysql_driver.c: BAD: 1.59.2.13.2.6...........GOOD: 1.59.2.13
mysql_statement.c: BAD: 1.48.2.14.2.7...........GOOD: 1.48.2.14

So the file versions are very close so there wasn't much changed between
them. It looks like the newer version either had a bug introduced that
causes this segmentation fault, or it is also possible that the way the
Ubuntu package was compiled is causing a problem I suppose? I don't know
much about the internals of this library so is there someone who is
familiar with the internals of PDO comment? Thanks.
