Bug description:  gethostbyaddr() crashes Apache on certain IPs

gethostbyaddr() crashes Apache (v1.3.24) when looking up certain IPs.
Example script:

echo gethostbyaddr('208.133.226.85');

Every other IP I've tried (so far about 40,000) didn't have any problems.
I tried the above line on another server running PHP4.2.2, Apache v1.3.26
and some form of Linux (2.4.9-31) and that had no problems.

Probably related: the Windows port of Webalizer crashes when performing
DNS lookups on the same line of the log file, so I suspect it's something
to do with DNS lookups in Windows (?).
