Hi all,
attached patch fixes using of coarrays as dummy arguments. The coarray
dummy argument was not dereferenced correctly, which is fixed now.
Regtests ok on x86_64-pc-linux-gnu / Fedora 39. Ok for mainline.
Regards,
Andre

Subject: [PATCH] [Fortran] Fix Rejects allocatable coarray passed as a dummy
argument [88624]
Coarray parameters of procedures/functions need to be dereffed, because
they are references to the descriptor but the routine expected the
descriptor directly.
PR fortran/88624
gcc/fortran/ChangeLog:
* trans-expr.cc (gfc_conv_procedure_call): Treat
pointers/references (e.g. from parameters) correctly by derefing
them.
gcc/testsuite/ChangeLog:
* gfortran.dg/coarray/dummy_1.f90: Add calling function trough
function.
