Well, I have mixed luck running under GDB... looking at the code, saw it
was trying to get the CGI info from the environment so set some
environment variables to fake up enough CGI environment to get it to
run.  But mostly wound up getting segfaults in expand_env on the
HTMLCONTENTTYPE stuff.

But I stumbled upon something that fixed my problem -- but not sure
why.  I edited the cgi-bin/bb-histlog.sh file, and added
"cd /tmp" before the meat of the script.  For some reason, I now seem to
have no issues.
