That was mostly random, it sometimes occurs even then.

I have found that increasing the stack size ulimit (from the default
4MB to 20MB) stops it though.

Is there a useful stack overflow debugging tool for NetBSD?
The valgrind port seems to have ground to a halt in 2007 :(

(A tester on Linux couldn't reproduce the problem even with a 1MB
stack size limit. I wonder why.)
