Reviewing the failures, I see several issues that might be relevant:

FAIL: MultiSource/Benchmarks/MallocBench/gs/gs.execution_time - is it about compile time again? I don't see any indication of a miscompile. If so, I see no alternative to making this transform enabled under option.

Same.

That might be interesting. Will try to reproduce that.
