>Description:
	
Something in nmh doesn't optimize properly with current's gcc. Running show,
if it was built with gcc4 and optimized with -O2 (the default), segfaults and
dumps core. This happens with any other nmh program that uses its custom
strcasecmp().
>How-To-Repeat:
	
Install and boot into current. I've seen this happen on 3.99.21 and 3.99.22.
Build and install mail/nmh.
Have some MH-format messages in $HOME/Mail/
show
>Fix:
	
Add 
CFLAGS+=-O1
to /etc/mk.conf. Rebuild nmh.
