cfexecd -d1: segmentation fault

[Andrew Stribblehill]

When I run cfexecd with the argument, '-d1' on its own, I get the
following:

# cfexecd -d1
cfexecd Debug mode: running in foreground

The backtrace looks like this:

Something fishy is going on, since SetDomainName() on its own works
fine. (It doesn't set the domain name -- just adds "wompom" to
VHEAP.)
