OK mainline? OK. I wonder whether a valid len/kind example should be added which uses such a PDT with non-default-kind integer. Tobias >> Gesendet: Freitag, 22.

Hi Tobias, > OK. I wonder whether a valid len/kind example should be added which uses > such a PDT with non-default-kind integer. the testcase pdt_4.f03 did actually check for the error message that gets removed and had to be adjusted. Removing just the dg-error does that job :-) Thanks, Harald > Tobias > > >> Gesendet: Freitag, 22.
