Bug #14089 Updated: use of mcrypt functions result in segfault of apache child

ID: 14089 Updated by: derick Reported By: mued@dev-edge.org Old Status: Open Status: Closed Bug Type: mcrypt related Operating System: GNU/Debian Sid PHP Version: 4.0CVS-2001-11-16 Assigned To: derick New Comment: I think you meant 2.4.6, if that is the case, upgrade to 2.4.17, which has a lot of bugs fixed. I'm closing this bug, because it's a merely a problem in the libmcrypt library itself. Please reopen if upgrading does not fix the problem.
