No, but regressions were recently introduced in the ACATS testsuite:
=== acats tests ===
FAIL: cb4008a
FAIL: cb41001
so this could be related.
Ada is not enabled by default so this is not surprising. It's OK for small
changes and bug fixes, but people making extensive changes to the compiler
should really consider enabling it (and it's a very good testbed).
