System: NetBSD webkeks.org 4.99.44 NetBSD 4.99.44 (WEBKEKS) #0: Wed Dec 26 23:52:39 CET 2007 firstname.lastname@example.org:/usr/src/sys/arch/i386/compile/WEBKEKS i386
When trying to systrace a program, the kernel crashes. This renders
NetBSD 5 unusable in an environment where security matters.
See https://webkeks.org/tmp/crash.jpg for a backtrace.
Tested with kernel checkouts from:
All give exactly the same backtrace.
Just run a program with systrace, for example systrace ls.
It seems the lock against itself has to be fixed.
