I've only tested with Perl 5.8.3, threaded. See this bug report that someone else filed for the Debian apache-perl package: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=236882 Looks like they're running unstable as well, so they'll have Perl 5.8.3 (threaded) as well. > > The trigger seems to be the fact that Mason includes this bit of code > > which _may_ be called at server startup: > > > > my $c = $r ? $r : Apache->server; > > @val = HAS_TABLE_API ? $c->dir_config->get($p) : $c->dir_config($p); > > does it matter which form you use if PERL_TABLE_API is enabled? Yes, if table api isn't enabled then dir_config just returns a hash, right? > what is the status of your config? I'm assuming that $c is an > Apache::Server object and not $r. Do you actually have a per-server > PerlSetVar at all, PerlSetVar foo 0, or PerlSetVar foo bar? This happens at server startup, so $c would be an Apache::Server object. In my case, the key it's looking for does not exist in the config at all.

Yeah, you'd think. I'm quite sure this is the culprit, though. I recompiled from the Debian source, but removed this one patch, and now there's no segfault. The reproduction recipe should be pretty simple, simply add this to your mod_perl config: PerlModule HTML::Mason::ApacheHandler Any recent of version of Mason should do, though I have 1.25 (well, really 1.26-to-be) installed here. -dave /*======================= House Absolute Consulting www.houseabsolute.com =======================*/ -- Report problems: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html List etiquette: http://perl.apache.org/maillist/email-etiquette.html
