I just tested lapack-3.1.0 and the problem is still there.

Yes, gcc version 4.3.0 20070216 seems to be very well done (at least for OSX 10.3).
I have forgotten to mention that the above results were obtained for lapack 3.0.
With 3.1.0 I got:

TESTING/csep.out: CST:    1 out of  4662 tests failed to pass the threshold
TESTING/csep.out: CST drivers:      1 out of  11664 tests failed to pass the threshold
TESTING/csep.out: CST:    1 out of  4662 tests failed to pass the threshold
TESTING/csvd.out: CBD:      1 out of   4085 tests failed to pass the threshold

TESTING/dsep.out: DST drivers:      1 out of  14256 tests failed to pass the threshold
TESTING/sgd.out: SXV drivers:     37 out of   5000 tests failed to pass the threshold
TESTING/ssep.out: SST:    1 out of  4662 tests failed to pass the threshold
TESTING/zgd.out: ZXV drivers:     24 out of   5000 tests failed to pass the threshold
TESTING/zsep.out: ZST:    1 out of  4662 tests failed to pass the threshold
TESTING/zsep.out: ZST:    1 out of  4662 tests failed to pass the threshold
TESTING/zsep.out: ZST drivers:      1 out of  11664 tests failed to pass the threshold
TESTING/zsep.out: ZST:    1 out of  4662 tests failed to pass the threshold
TESTING/zsep.out: ZST drivers:      1 out of  11664 tests failed to pass the threshold

but I did not have to patch SRC/slarre.f to avoid an infinite loop in ./xeigtstc < sep.in
(note this file have been changed a lot between the two versions).
