Bug Type: mhash related
Operating System: FreeBSD 7.2 amd64
PHP Version: 5.2.11
New Comment:

Well, running something does not require installing it:

# make && sapi/cli/php -v

And are you somehow enabling ZTS too? And you're sure you're loading
the mhash.so from the same build? (I can't reproduce this..)

ok here
http://www.pastebin.cz/e9a52bce5e4288
is the gdb output on the core dump of php 5.2.11 without the suhosin
patch with debugging symbols enabled.
If I remove mhash.so from the extensions php runs without problem. If
mhash is enabled it produces the segmentation fault (heap overflow).
Mhash package works normally and python mhash module works as well so
from what I can see it is probably some kind of issue in php5-mhash.

PS: And yes, I can run it from commandline but I had to recompile php
without the suhosin patch included ;)

You can't run the thing on command line..? I thought that's how you
really meant it to be reproduced: # php -v ? (please don't reply before
you have real feedback)

it was with suhosin patch compiled in but with USE_ZEND_ALLOC set to 0.

I can post a test without suhosin but that will have to wait until
night - I see this behaviour on a production machine so I can not allow

php to segfault during work hours and I don't have a spare one to
reproduce the problem.

Was the backtrace with or without the suhosin patch? (I'm guessing
without?)

if by 3rd party patch you mean suhosin then yes, bud instead of the
error message it segfaults.
