I saw these fail on the glibc shadow stack branch today, and I also saw this one failing: FAIL: nptl/tst-robustpi8 It spit out: mutex_timedlock of 41 in thread 1 failed with 22 child did not die of a signal in round 1 After the fix here I saw the others pass, but still not tst-robustpi8. Not sure if it is some shadow stack complication. I can try to dig in tomorrow if the problem doesn't jump out.
