I experienced the same Panic, when I was learning programming language 
`expect'.

I will send the `expect' program which caused panic.
It's short program.
>>>>>>>>>>>>>>>>>>>>>>>>>>
#!/usr/local/bin/expect --

spawn -noecho show
interact
<<<<<<<<<<<<<<<<<<<<<<<<<<
This program is just spawning MH command `show',
and interact with it.
This program often (1 out of 2~3 times) causes panics for my machine,
and I gave up learning `expect'.

My machine has ASUS P6NP5 with Pentium Pro.
