Re: [Patch, fortran] PR37336 (Finalization) - [F03] Finish derived-type finalization

Hi Paul,

thanks for attacking this.

I haven't looked at the actual patch, only tried to check the new
testcases with other compilers.

Could you specify which version of Intel you tried?

Testcase finalize_38.f90 fails for me with ifort 2021.5.0 with:

131

This test also fails with crayftn 11 & 12 and nagfor 7.0,
but in a different place.

(Also finalize_45.f90 fails with that version with something that
looks like memory corruption, but that might be just a compiler bug.)

Thanks,
Harald
