Invalid binary operation and USE statement order

[Øystein_O_]

Hi,

I have attached an example that should compile, and there are several ways to work around the bug. The comments on lines 229 through 235 show how the order of the USE statements determine if the code compiles or not.  It also compiles if I remove a subroutine from an interface ( line 139), but that is not a work around for my project.

This is the output from the compiler

C:\wdir>ifort invalid_binary_error.f90

Best regards,

Thanks for the nice test case and your investigation notes. I am pretty sure this is the same compiler bug reported here, but it is not yet fixed. I will add this to the existing issue DPD200374263 and ping the developers for status.
