  That's one thing that can cause it.  Another cause is interference from
system-call-hooking software such as anti-virus and firewalls.  What the error
message is trying to tell you is that during the fork operation, it has been
unable to duplicate an area of memory from the parent process into the child
process.  Since it's a requirement that fork() create child processes
identically laid out to their parents, this is a fatal situation.

  Good.  The next things to try would be running a rebaseall[*], and checking
the BLODA[**].

  Yes, Vista isn't well supported; not a lot of the list members even have it!

    cheers,
