Hi, all,

I decided to try out current compiled from today's sources. After doing 
some work, I ended up getting a panic:

panic: Segv in kernel mode: pc 8017a36b addr 89ce6050
Stopped in pid 0.4 (system) at  netbsd:trap+0x4fc:      movl    $1,

This is after 20 minutes of work. 4.99.19 ran for months and compiled a 
couple of thousand pkgsrc packages without problems...
