Runtime tests fall over when run with address sanitizer - Part2 #89

Open adam-fowler opened 3 years ago

adam-fowler commented 3 years ago

Once #88 is merged there are still a number of ASan issues. The tests that fail are

All of these fail when accessing data in NominalMetadataType. The first fail is in numberOfFields. Here is the ASan output

Test Case '-[RuntimeTests.GetSetStructTests testGetSimple]' started.
