Sigh. Probably take me a week to cut the code down so far that I could
give something out. I know that 'seeing the code' is a basic first step
and not being able to do that really bites into any ability to diagnose
though, so I understand.

Yes. It compiles fine under intel and xlf (many versions over the years).

In reference to your other comment about the error pointer being misplaced
(not pointing at a specific variable), I have tried limiting the use
statement to a single variable as:

use the_module, only : var

for each of the variables in the use line one at a time. They all trigger
the same error.

The trouble with the error message that I'm having is that it implicates
an equivalence of some sort, but there is no equivalencing going on that
I can see. Can you speculate on what gcc defines as an equivalence or
equivalence problem that is so much more general/different than other compilers?

I've tried turning up warning reporting, but nothing pops out there either.

Thanks,

Andy
