Massive regression failures

I am seeing massive regression failures on a freshly compiled, initdb'ed
version of CVS:

16 of 81 tests failed, 1 of these failures ignored.

The first failure I see is:

COPY COPY_TBL FROM '/usr/var/local/src/gen/pgsql/CURRENT/pgsql/src/test/regress/data/constrf.data';
- ERROR: copy: line 2, CopyFrom: rejected due to CHECK constraint copy_con
SELECT * FROM COPY_TBL;
x | y | z
! ---+---------------+---
! 4 | !check failed | 5
! 6 | OK | 4
! (2 rows)

Are others seeing this? Cause?
