[TriLUG] Apache: Segmentation fault errors

[Paul G. Szabady]

James,

Excuse my ingnorance as I've not used httpd-debug nor gdb before.  I'm
obviously missing something.

As you can see below, when I created the new rpms, I did get and install
the httpd-debug rpm.  Hence, my confusion and follow-up email.

Maybe I defined it wrong in the httpd.spec file before compiling from source?

EXTRA_CFLAGS='-g'
export EXTRA_CFLAGS

BTW, you did send an email, which is why I'm trying this.   ;-)
