CGI header mod_perl 1.99_13
hi all,
i test all my scripts which this version of mod perl
and i have the message :
[notice] child pid 3541 exit signal Segmentation fault (11)
in the error_log all the times but not the first one when i call the script
if i remove
print header();
and put
print "Content-Type: text/plain\n\n";
it's ok
does some thing specific to do with CGI.pm (v 3.04) and mod_perl ?
#-----------------------------
#!/usr/bin/perl -w
use strict;
use Carp ();
local $SIG{__WARN__} = \&Carp::cluck;
use CGI qw(:standard);
# notice] child pid 3541 exit signal Segmentation fault (11)
print header();
# ok :
# print "Content-Type: text/plain\n\n";

You have a bunch of older mp2 installs lingering around. I won't be surprised
if you get the wrong libraries loaded. I'd suggest to nuke any previous
mod_perl installations.

The segfault backtrace is missing. http://perl.apache.org/bugs/ explains how
to get one.
But first please adjust your script to do:
my $header = header();
warn "[$header]";
print $header;
and show us what has CGI.pm generated as a header (hint: it'll go into
error_log). It's possible that I can't reproduce the problem, because our
output of header() don't match.
I have an idea where the problem could be (as I've completely rewritten the
header parsing code just a week ago), but I need to have the input that
triggers that problem.
Thanks.

Sorry Arnaud, I can't reproduce it. Please file a proper bug report:
http://perl.apache.org/bugs/
BTW, you should start to get used to the mp2 syntax:
s/PerlSendHeader On/PerlOptions +ParseHeaders/
;)
