monit 4.8 segfaults on Redhat EL4

[Mike Jackson]

System is Redhat EL4. It's running on an Opteron processor, with the amd64 
install of Redhat.

Configured monit with:  --with-ssl-lib-dir=/usr/lib64

Nothing appears to be out of the ordinary during the build process. However, 
it segfaults when run. This gets logged to /var/log/messages:

May  4 10:03:58 bonsai kernel: monit[26655]: segfault at 000000000000681f 
rip 0000003106b6fd00 rsp 0000007fbfffedc8 error 4

I get this when I run it through gdb:

I'm not a C programmer, so I don't have much idea what all that means. I can 
provide other details if you need. I also ran it through strace, which 
produces volumes of output, but I won't send that unless someone needs it.
