Subjectniceness buglet?
Hi there.

I have to admit that I'm puzzled by this, and I don't know where else
to ask, so here goes...

One of my interests is in MUSH's (Multi-User SHells), and in relation
to one of them that I'm a regular on, I run what's called a bot that
pretends to be Eliza the Psychotherapist.

Since the current version thereof sometimes runs away with processor
time, I decided to 'nice' it to a low priority - and this is where the
problems started...

I can RELIABLY cause Eliza to coredump by simply running the following
command:

Q> nice -n 15 bot Amush.CX 4190

Note that "-n 15" as that is CRITICAL - any value other than 15 (at
least, those in the range 5 to 19) and Eliza runs fine - I'm currently
running her with 16 instead of 15 - but with 15 there, she coredumps
every time...

For reference, ver_linux produces the following:

-- Versions installed: (if some fields are empty or looks
-- unusual then possibly you have very old versions)
