CGI segfault

[Kyle Gordon]

Hi all,

I sent this mail to the -users list about a week ago, and in retrospect
it's probably more of a developer question.

I have just compiled up v2.5 on Suse Linux Enterprise Server 9.3, and
installed Nagios with almost complete success. The only problem is the CGI
files that are failing to run. They segfault with the following data from
strace. selinux is disabled on this machine, and I've been running the
commands with the following...

REQUEST_METHOD=GET ./status.cgi

The output is all good HTML, until this point...

write(1, "<!-- Produced by Nagios (http://"..., 93<!-- Produced by Nagios

My debugging skills aren't the best, but hopefully this is the relevant
information. Let me know if any more info is required.

Any advice would be greatly appreciated :-)
