Hi Lorenzo,
Issue 1 is a bug in the implementation of Optional that I introduced a
couple of days ago. This has been now reverted, but we will still see the
error reports for the next couple of days in the test matrix.
Issue 2 seems to be the communication problem between the compiler and the
standard library, but I do not know anything specific.

Regards,
