This discussion is going to be generic until I can create a suitable small test case. I am just hoping somebody has seen this problem before and can point me in the right direction.
I am attempting to create a TYPE and a TYPE which extends the original. I then wish to use the second (child class) in many places around my fixed-form Fortran code. I have been getting the warning message
warning #8499: The procedure has a dummy argument that is polymorphic. Required explicit interface is missing from original source.
Then comes the internal compiler error. If I put an explicit interface in the code, the warning disappears but the ICE remains.
I know these statements are general, but my current "small" example has a PROGRAM, two SUBROUTINEs and 16 modules. Once I start paring it down, I have not had much luck reproducing the ICE.
Any help would be appreciated.
