Segfault/double-free crash in python-pysqlite2 in apache2

Bug #152129 reported by Marcus Bointon on 2007-10-12

Affects		Status	Importance	Assigned to	Milestone
	python-pysqlite2 (Ubuntu)	Invalid	Undecided	Unassigned
	trac (Ubuntu)	Invalid	Undecided	Unassigned

Bug Description

python 2.5.1, libapache2-mod-python 3.2.10, python-pysqlite2 2.3.2-1, apache2 2.2.3-3.2build1, trac 0.10.3-1.

Using all standard ubuntu packages, nothing odd. Hitting trac's start page gives an immediate apache2 segfault which appears to be in python-pysqlite2. I also tried a later version of trac from source, but made no difference.

Here's the segfault from the apache2 error log:

Looks like pysqlite2 pulled in libsqlite3 which is correct. It appears that mod_php is using plain old libsqlite. My guess is that it's an interaction between these two.

Also, apache2, pysqlite2, and libapache2-mod-php5 all have new versions since you reported the bug. Is it still reproducible, or was it perhaps due to only partially updating the system?

Not a Trac bug. Either mod_php or pysqlite2 is my bet.
