I think this might be some problem with Perl, so I'm submitting this here. The same configuration works on a Debian server system. Attached to the failing Apache with GDB produces the attached backtrace. Unfortunately I'm not quite clear how to produce a simple testcase for this matter. Reproducible: Always Steps to Reproduce: 1. Setup of Movable Type 5.01 as a mod_perl handler 2. Create a new Page 3. Click on Publish or Preview Actual Results: Blank page, Apache segfaults Expected Results: Preview working Some application versions & vendor: apache2-mod_perl 2.0.4-45.1 obs://build.opensuse.org/Apache perl 5.10.0-72.5 openSUSE apache2 2.2.13-2.3.1 openSUSE -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=588338 http://bugzilla.novell.com/show_bug.cgi?id=588338#c1 --- Comment #1 from Michael Schröder 2010-03-16 09:36:13 UTC --- That may indeed be a bug in perl's regexp engine. Very hard to debug without more input. (If it works on a debian system, do they really use the same perl version?) Can you please put "PerlSwitches -Dr" in the mod_perl config to get some regexp debug output (probably in one of the apache log files)? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I hoped to see the text/regexp that caused the segfault, but it's not in the log ;-( My guess is that it crashes in MT's translate_naughty_words() function. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
