Further datapoint: on a lark, I tried 8k stacks, and my symptoms changed - tst-mutex7 never failed, but running tst-mutex7a in a tight loop crashed the box reliably though differently. I then recompiled with no debug options enabled, and ran all mutex tests in a loop for a couple of hours with no crash.
