Yes, weird.
I'm hunting any remaining bugs related to <Perl> Sections.
Can you please test the attached patch vs 1.26? (please forget about the
patch posted by Michel, it is mine and in CVS now, but in this I'm
trying a more radical approach and checking for the proper nesting of
directives)
Then try to reproduce your problems under MOD_PERL_TRACE=ds (see the
DEBUGGIN section in the mod_perl man page), thats is, compile mod_perl
with PERL_TRACE=1 and run your Apache in single process mode:
# MOD_PERL_TRACE=ds <path_to_your>/httpd -X
And please post the generated log.
Regards.
