Conflict between SSL in php3/IMAP module and mod_ssl
Last modified: 2007-03-26 23:42:58 EDT
I have found a conflict between the php-3.0.18-1.6.x when both the IMAP
module for php (which is linked with the SSL libraries) and mod_ssl (also
linked with the SSL libraries) are both included.
The error shows up in the ErrorLog as:
[Fri Mar 23 18:22:08 2001] [notice] child pid 9924 exit signal
Segmentation fault (11)
and the server returns no data to the client.
A quick-and-dirty patchthat allowed SSL services to work was to remove
-lssl from the link line as follows:
--- php.spec Fri Jan 19 11:01:28 2001
+++ php.spec-rwm Tue Mar 27 22:31:49 2001

# LDAP module
perl -pi -e 's/HAVE_LDAP 0/HAVE_LDAP 1/g' config.h
Note: I have not investigated the problem sufficiently to know why this
change to the link line allows things to no longer core dump, just know
that it does.
Which version of OpenSSL was the mod_ssl package built against? If it was not
identical to the version used to build PHP (0.9.5a-2.6.x), then odds are that
the two are not binary-compatible (structure sizes are often different depending
on which algorithms are enabled).
Both apache and php were recompiled on the same computer from src.rpm's
originating from RedHat with minor patches.
For Apache I made the following changes - I can attach the SPEC file or make a
diff if that is appropriate.
* Fri Mar 23 2001 Russell McOrmond <firstname.lastname@example.org>
- Upgraded to Apache 1.3.19, mod_ssl 2.8.1
- removed mod_rewrite fix (Now part of Apache)
- removed glibc22 patch.
* Wed Oct 18 2000 Nalin Dahyabhai <email@example.com>
- apply fix for references in rewrite expansions from Tony Finch
