Nothing noticeable.  The only lines that are in the executable and not
acml_mp are:
      libacml_mp.so => /usr/local/lib64/libacml_mp.so
      libgcc_s.so.1 => /lib64/libgcc_s.so.1
and the only line that is in acml_mp but not acml is:
      libgomp.so.1 => /usr/lib64/libgomp.so.1

No other differences (checked by diff), except for the hex. grobble in
brackets.  Checking the binary for the lapack version shows that the only
difference from the failing one is the ACML libraries are replaced by
LAPACK and BLAS.

It could still be a gcc version problem, of course, but not in that respect.

Regards,
Nick.
