Hello, I was wondering if anyone is working on solving PR 52347? "ww mutex class mismatch" I'm getting it averaging about once every other working day on my main machine.
8.99.34 did crash, but I couldn't get a good backtrace. This is a backtrace for a 8.99.30 a few days ago. # crash -M netbsd.34.core -N netbsd.34 Crash version 8.99.34, image version 8.99.30.
