[mp1] segfault with Perl 5.8.1 and mod_perl 1.29

[Joachim Feise]

Hi,

on my Linux system (Slackware 9.0) Apache segfaults in mod_perl as soon as it
receives the first request.
This started after I upgraded to Perl 5.8.1 (from 5.6.0).
The Apache version is 1.3.28, mod_perl 1.29.
I appreciate any help.
