Hi,
after i recompiled the newest versions of perl, apache and mod_perl on
my home computer with the appropriate debug switches, i cannot reproduce
the Segmentation Faults any more, too.
At my machine at work i found out that the problem had to do with the
DBI module, which i additionally loaded. After installing the newest
version of DBI and/or not loading this module, no Segmentation faults
happened any more.
Concerning the PerlOptions:
>From the results below i conclude:
+Parent means everything is new in the virtual host. You have to add the
libs and paths you need all there.
+Clone means everything is "cloned" from the main configuration. To add
a "private" lib path you have to call a second startup script with the
lib path you need included. The PerlSwitches -Mlib=.. in the virtual
host section are ignored.
+inherit makes no difference at all (probably i did/do not understand
that option)
So after everything is "clear" now (i have to sleep one night over it) i
will continue moving from 1.3 to 2.0.
Thanks for your help
Helmut

I can't reproduce it. Please send in the backtrace from the core file
and the
rest of the details. See:
http://perl.apache.org/docs/2.0/user/help/help.html#Reporting_Problems

If you use the +Clone, it already inherits everything from the parent,
including @INC. So you don't need the last 3 lines. It works just fine
for me
with 'PerlOptions +Clone'.
Perhaps you can send in your httpd.conf after you have reduced it to the
very
minimum (including the minimal startup.pl that still reproduces the
problem)
