Bug #757
closedinternal server error gives 200 OK sometimes
Description
Config: OSX/freebsd-kqueue/cgi/setenv
Perl: v5.8.6
If the CGI script fails, it somitimes gives a 200 with empty page instead of 500, the errors to STDOUT clearly come into the log that an error DID happen.
script:
#!/usr/bin/perl use base 'some_module_not_found'; print "Content-Type: text/plain\r\n\r\n"; print "You really have some_module_not_found.pm ?!\n";
tcpdump:

I just notices mod_rewrite was enabled, after disabling it, the problem was away

after enabling it back again, the problem was not back, which is odd...

after some time running (10 minutes), the problem came back, it randomly gives 200/500
