Our environment:
	Sun4/370 & 4/330 machines (4 kernaal NOT 4c) running 4.1.1 Sunos.
	Mit X11R4 pathc level 18, andrew patch level 8 (compiled with -O).
	Not using resolver libs or AMDS.  

Help command fails with illegal instruction if any UPPER case letters are
used in the help argument.  If only lower case leters are used help appears
to work correctly.  If select help on ... is choosen from the running help
menu and UPPER case letters are used it also crashes.

We have tried compiling without -O and with -DDEBUGGING (and adding a few debugging lines of our own and confirm that the illegal instruction occurs
on the call (or in) the tolower() routine in LowerCase.  We have 'cut' out the
LowerCase routine and used it in a small test program and it works fine.
To concur with your conclusion ....VERY STRANGE INDEED.  
If there is any way we can assist let us know ...
