EMACS 18.50 Hanging under VAX / Ultrix 2.2

[Karl A. Nyberg]

Thought to pass this on in case anybody else has seen of does see this in
the future.

MicroVAX II/Ultrix 2.2 (with patches), EMACS version 18.50.

After the system crashed last night, EMACS exhibited this strange behavior.
It would start up, but attempts to use commands (in particular find-file,
C-X C-F) would just hang there.  It would accept the filename, and the
cursor would reposition to the beginning of the echo line, and just sit
there.  Only way out was to C-G C-G, and then kill the job.  I thought maybe
there was something wrong with the system, memory, files, etc. so I
rebooted, ran fsck, and even ran the memory exerciser enough to hopefully
clear out all of memory with no improvement.

Restored an executable version from tape with the same results.

Recompiled from scratch, and everything APPEARS to be working again.
