The same crash happens in d15-4 (with a different line number: mini-runtime.c:1756).
Comment 1 Rolf Bjarne Kvinge [MSFT] 2017-10-04 14:45:08 UTC
This only happens on watchOS in release mode.
Comment 2 Rolf Bjarne Kvinge [MSFT] 2017-10-04 16:43:16 UTC
d15-3 crashes even earlier in the test run, so this is most likely not a regression.
