Your change itself is fine.
The PR was originally about a type mismatch between the gfortran library 
and the call generated by the front-end.
As the code generated contains a cast, I think it’s fine as well.
But please give Thomas (bug reporter) one more day to comment on this.
Then I think you can proceed.

Thanks.
