Bug#598876: zdrot bug

[Freitag, Chip]

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.
