Package: libapache2-mod-php5
Version: 5.2.0-8+etch15
Severity: important
Originally this entire setup was on Etch - problem free. After an upgrade to a different machine running Lenny we saw "zend_mm_heap corrupted" errors and the reported segfaults. After a downgrade to Etch-n-half (for hardware reasons) we dropped the "zend_mm_heap corrupted" error but the random segfaults remain.
We have analysed child activity prior to a selection of the segfaults, and have spotted no pattern although there is more often than not a gzipped js or css file being served up shortly before the segfault.

Version: 5.3.3-7
Hi,
since lenny is oldstable it will not get any updates now (except
security)[1], I am closing all segfault bugs filled against php5 in
lenny. (This is kind of saying that we don't care much about php5 in
lenny anymore).
If you believe the bug is still there, please provide evidence[2] and
a (preferably complete) test case with up-to-date squeeze (and/or
testing or unstable) version of php5 and reopen the bug.
O.
