Hi!
some boilerplate:
NYTProf-4.03
mod_perl 2.04
Archive::Zip 1.30
DBD::Pg 2.17.1
perl v5.12.1
linux x86_64
First off it seems to work if I run it from the command line: "perl
-d:NYTProf -T index.cgi".
When I Add "PerlModule Devel::NYTProf::Apache" to my conf I get the
below segfault:
Program received signal SIGSEGV, Segmentation fault.

Ok lets try disabling some things:
# NYTPROF="subs=0:blocks=0:stmts=0:savesrc=0" httpd
Segmentation fault
OK so I thought what happens if I try start=no:
# NYTPROF="start=no" httpd
Undefined subroutine &main::1 called.
END failed--call queue aborted.
If I take out my preloading of modules in my startup file it seems to
work. So I tried figuring out if there was a single module that was
bad... after much sweating (It preloads ~900 modules). I found this
simple test case to demonstrate the problem:
PerlPassEnv NYTPROF
PerlModule Devel::NYTProf::Apache
PerlRequire empty.pm
<FilesMatch ".cgi">
SetHandler perl-script
PerlResponseHandler empty
PerlSendHeader On
</FilesMatch>
empty.pm:
package empty;
use Archive::Zip();
use DBD::Pg();
sub handler
{
print "Content-type: text/plain\n\nhi\n";
return 0;
}
1;
Basically I can use Archive::Zip or DBD::Pg, but not both at the same
time :-) Any Ideas?
