Hi Scott
As he wrote "Sorry for my terrible english...",
I assume it was not intentional offensive.
Coming back to your issue, it is really curious that gfortran compiles
the code but behaves wrongly, I was expecting it rejects the code
if not in line with latest standard.
I saw rejected code with lapack some time ago, and the correction was
trivial. But compiling and not working is a serious gfortran bug.
Have you a "short test case" ?

Marco
