hi Stas, here the complete bug report,
-------------8<---------- Start Bug Report ------------8<---------- 1. Problem Description:
i have the message :
[notice] child pid 3541 exit signal Segmentation fault (11) in the error_log not the first one when i call the script but when i have the message, second times ou third time i call the script, the Segmentation fault (11) message always apear in the log.
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 ?
