Description of problem:
Dies in compiling the standard BLAS tester on POWER4 architecture:

gfortran -O -m64 dblat3.f

How reproducible:
Always


Steps to Reproduce:
1.  Download dblat.f from netlib address above
2.  gfortran -O -m64 dblat3.f on POWER4

Actual Results:
octavius>gfortran -O -m64 sblat3.f
sblat3.f: In function ‘schk2’:

Expected Results:
produce object file

Additional info:
Problem seems to go away if I compile with no optimization.  Problem is definitely arch-specific: I compile these tester routines daily on a variety of architectures, using both standard gnu compilers and Fedora versions.

FC4 is not supported any more for almost a year now.  This compiles just fine
on FC6.
