Hi Paul, thanks for attacking this.
I haven't looked at the actual patch, only tried to check the new testcases with other compilers. Am 03.02.22 um 18:14 schrieb Paul Richard Thomas via Fortran:
I have tried to interpret F2018 7.5.6.2 and 7.5.6.3 as well as possible. This is not always straightforward and has involved a lot of head scratching! I have used the Intel compiler as a litmus test for the outcomes. This was largely motivated by the observation that, in the user survey conducted by Steve Lionel, gfortran and ifort are often used together . Therefore, quite aside from wishing to comply with the standard as far as possible, it is more than reasonable that the two compilers comply. On application of this patch, only exception to this is the treatment of finalization of arrays of extended types, where the Intel takes "If the entity is of extended type and the parent type is finalizable, the parent component is finalized" such that the parent component is finalized one element at a time, whereas gfortran finalises the parent components as an array. I strongly suspect that, from reading 7.5.6.2 paragraphs 2 and 3 closely, that ifort has it right. However, this is another issue to come back to in the future.
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
