gfortran compiler problems

[George Rinker via Gcc-help <gcc-help@xxxxxxxxxxx>]

I've been having some problems getting my source code compiled with 
gfortran. In particular, I get inexplicable fatal errors with pointers 
to code lines that are legal and have compiled many times before, and 
the error messages are not informative and hang the command shell I'm 
using (cmd.exe). There seem to be problems with stderr, stdin, and 
stdout in the compiler, presumably due to incompatible terminal 
assignments. I've been writing Fortran programs continually for almost 
60 years (since 1967), so it's not like I'm new at this. Is there a 
forum or something where I can get advice about this sort of thing?
