Just for the record, an ACML customer ran into this in ACML-GPU 1.1.1. The problem was discovered to be the code generation issue in ZDROT, and arose because the library was built with GCC/GFORTRAN 4.4.1. On a hunch I verified that the problem also occurs with sdrot. Using -O0 to build resolves the problem. I was about to submit a bug report to the GCC people, but it appears that this has already been done. ACML-GPU 1.1.2 resolves the problem by using the less aggressive optimization for these two modules.
