sandra at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sandra at gcc dot gnu.org --- Comment #16 from sandra at gcc dot gnu.org --- There seems to be no actual v2 patch at the link posted previously https://gcc.gnu.org/pipermail/fortran/2021-April/055991.html or the recent mail pinging that patch, and the original version at https://gcc.gnu.org/pipermail/fortran/2020-February/054001.html doesn't apply cleanly. Can you repost the patch or attach it to this issue? I think this PR may be the same issue that is affecting gfortran.dg/ts29113/interoperability/cf-out-descriptor-3.f90 gfortran.dg/ts29113/interoperability/cf-out-descriptor-4.f90 gfortran.dg/ts29113/interoperability/fc-out-descriptor-4.f90 from my new TS29113 testsuite https://gcc.gnu.org/pipermail/gcc-patches/2021-July/574115.html and I'd like to try out the proposed fix. My own diagnosis was "Fortran function with C binding fails to automatically deallocate intent(out) allocated allocatable on entry when called from C". These testcases additionally trigger nasty errors from the memory allocator.
