Ok, generic subject. Here's the scoop
linux kernel 2.2.5-ac1
glibc 2.1.1
egcs 1.1.2
After compiling openssl and installing it, after doing the mod_ssl and
apache compilation,
I attempt to generate a certificate from within apache as "make
certificate TYPE=custom".
After seeing the error, I added some echos to the script, here's that:
(different attempts,
different lines)
STEP 1: Generating RSA private key for CA (1024 bit) [ca.key]
"#303 /usr/local/ssl/bin/openssl genrsa -rand
/var/log/messages:/etc/hosts:/etc/resolv.conf \
-out ../conf/ssl.key/server.key 1024"
So. pop up the handy dandy gdb. run it and bt returns:
(gdb) r genrsa -rand /var/log/messages:/etc/hosts:/etc/resolv.conf -out
../conf/
ssl.key/server.key 1024
Starting program: /usr/local/ssl/bin/openssl genrsa -rand

---------
The reason why I rebuilt openssl/mod_ssl/apache is because apache is
segfaulting on startup with ssl enabled.
Any ideas, comments, suggestions, requests? Please let me know.
