1. Problem Description:
Apache 2 SEGVs during the test run (see core dump at the end), then tests fail randomly (Failed 23/221 test scripts, [...] 77/2272 subtests). t/logs/error_log is absolutely helpless (the only unexpected message is the usual "child pid 27077 exit signal Segmentation fault").
This is Linux/i386 2.6.5, Debian stable, plus Perl 5.8.5 home-built (./Configure -de -Dotherlibdirs=/usr/share/perl5 -Dversiononly - -Duseithreads -Dusemultiplicity) and Apache 2.0.52 with worker MPM from Debian backports (www.backports.org).
