Well, I only found one (and a larger number of warnings, which can
presumably be ignored).

The error is

ERROR: 'a2' argument of 'max' intrinsic at (1) must be INTEGER(4)


You are mixing arguments of different types, e.g.,

  MAX(integer_variable, real_variable)

The error message appeared because ITT is not INTEGER(4). A workaround
(or solution) would be:

  ITMAXf =  max(ITMAXf, int(ITT(Kf))

I have no idea whether that makes sense or not as I don't know the context.

PS: The error message is in line with the error given by other
compilers. One problem is the ambiguity of the return value. Should an
INTEGER or, e.g., a REAL be returned by MAX?
