Subject: mp2, apache 2.0.46, perl 5.8.0, & gcc 3.3 core dumps on solaris 8


-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:

  gcc 3.3, solaris 8, perl 5.8.0, apache 2.0.46, mod_perl 1.99_10
  make test failed
  I used gcc 2.95.2 built perl5.8.0 and mod_perl and it works ok.
  however, I upgraded gcc 3.3 and rebuilt perl, apache, and mod_perl.
  it still core dumps on me.
  apache 2.0.46 works ok by itself.
  I have setup my PATH and LD_LIBRARY_PATH ok.
  what could I do wrong?
  
$ cat startup.pl # is there any bad code in my startup.pl file?
#!/s5/twh/perl580/bin/perl

use Apache2 ();
use lib qw(/s5/twh/apache2/perl);
use ModPerl::Util (); #for CORE::GLOBAL::exit
  
use Apache::RequestRec ();
use Apache::RequestIO ();
use Apache::RequestUtil ();
  
use Apache::Server ();
use Apache::ServerUtil ();
use Apache::Connection ();
use Apache::Log ();
  
use APR::Table ();
  
use ModPerl::Registry ();
  
use Apache::Const -compile => ':common';
use APR::Const -compile => ':common';
1;
===end startup.pl
  Thanks in advance.
