Well, I have some failures even with 4.1.2, attached below.
I have hundreds of failures scattered all over the tests.
Often I run a few different builds in parallel, with different obj/build
directories. Is it possible that the test infrastructure writes
something to the source directories or some common temp directory? That
could confuse things when doing parallel build/test and would explain
all these failures. When I don't run in parallel, things seem to work
much better.
