--- Comment #3 from Alex Bligh <a...@alex.org.uk> --- Looks like I spoke too soon. This *DOES* occur on 2.4.10, it's just more difficult to replicate. Of course it replicates just fine with my real-world example. Here's a backtrace of it dying on 2.4.10. I will try to amend the test case to replicate this. In the meantime is there anything further I can do to debug this? root@nimtest:~# gdb --args /usr/sbin/apache2 -k start -X -e Debug GNU gdb (Ubuntu 7.7-0ubuntu3.1) 7.7 Copyright (C) 2014 Free Software Foundation, Inc.
