all the recent ones are in reflection tests in MT. cc @BrzVlad any ideas ?
Note reflections tests are disabled as active issue now for MT, otherwise this would report many more

Note, it's not the same stack trace, there are 2 different fails, which means that (possibly another) OOM corrupted the memory for the GC.
Maybe malloc returned -1 and the return value was not tested (for which we don't have the stack trace)
