[erlang-questions] Desperately looking for official Erlang tests results

[Björn Gustavsson]

Did you run Erlang from the git repository/source
tree or did you do "make release" and run it from
there?

A few tests cases will fail if you have not done
"make release". (One example is
xref_SUITE:md/1 in tools.)

I think that the best way for us to help you is
if you can share the names of the failed
test cases in the following test suites:

emulator_test
stdlib_test
kernel_test

We should be able to tell you which ones
that are most likely real bugs, and which
ones that fail because of envioronmental
issues.
