I'd like to report a bug I found in pgf95 12.4:

Some codes that were able to be compiled under pgf95 10.9 failed when compiling with pgf95 12.4. I've attached the code sample in a tarball. The short description about what I think the issue is that compiler failed to compile a module that tries to refer to KIND parameter defined in another module (via use), if the former contains interfaces with *many* functions. Note that the compile might still work if the number of subroutines in the interface are reduced... With previous version (10.9) I don't have any issues compiling the same code.

To repeat the error, just try to compile codes found in the tarball:

First, trying to compile typeSizes.f90 as object and link it with arrays.f90, using the old version (10.9) of pgf95:

pgf95 -c -o typeSizes.o typeSizes.f90
pgf95 typeSizes.o -c -o array.o arrays.f90

PGI 10.9 has no problem compiling these codes. However, when using version 12.4, I got error messages:

pgf95 -c -o typeSizes.o typeSizes.f90 (this step is still ok)
pgf95 typeSizes.o -c -o array.o arrays.f90

Error messages:

PGF90/x86-64 Linux 12.4-0: compilation aborted

As you can see, the whole content in arrays.f90 is basically doing the same thing, yet the compiler only start complaining later ( after line 2000+ ).
Even if I rearrange the order of the function calls. The compilation still fails at the same line (but actually with different code).

Thanks for the report Jason. I will take a look at this and let you know what we find out.

I have been able to recreate the issue and have filed a bug. The bug number is: fs18788

[jtull]

TPR 18788 - Use-associated parameter not visible: -Non-constant expression where constant expression require

was fixed in the 12.8 release.
