Hello Ingo,
see Jason's answer in November:
http://icl.cs.utk.edu/lapackforum/archives/lapack/msg00182.html
The problem is that ESSL BLAS routines do not call the XERBLA error
handler. (IBM guys like to be a little bit original from time to time.)
The BLAS tester performs wrong calling sequence on the BLAS routines and
then tests that the XERBLA error handler is called with the correct
routine name and the correct error information.
What is happening with ESSL is that when the tester is making non conform
calling sequences to the BLAS, ESSLBLAS complains, and the tester
complains ... A total mess.
Well so either as Jason has suggested you contact IBM and tell them that
having a call to XERBLA from ESSL so that you can trap error messages
would be really useful or in (for example) sblat2.in there is FLAG TO TEST
ERROR EXITS. Just set it to F. (I have never tried but this should work,
would be glad if you have time to try.)

Hello,

The AIX version seems to exit directly on the wrong calls of type
CALL SGEMV( '/', 0, 0, ALPHA, A, 1, X, 1, BETA, Y, 1 )
so that no error handling is possible.
With regards
