Attached is the test-suite.log file from a failed test:
I am not sure about the cause. It's either over-zealous optimisation in
clang or a subtle bug in libmill. However, it seems that using
optimisation level -O1 instead of -O2 fixes the problem.
As a temporary measure I can add a check for clang into build system and
use -O1 if it is found.
What do you think?
