gfc_omp_predetermined_sharing cases the associate-name pointer variable to be OMP_CLAUSE_DEFAULT_FIRSTPRIVATE, which is fine. However, the associated selector is shared. Thus, the target of associate-name pointer should not get copied. (It was before but because of gfc_omp_privatize_by_reference returning false, the selector was not only wrongly copied but this was also not done properly.) gcc/fortran/ChangeLog: PR fortran/103039 * trans-openmp.cc (gfc_omp_clause_copy_ctor, gfc_omp_clause_dtor): Only privatize pointer for associate names. libgomp/ChangeLog: PR fortran/103039 * testsuite/libgomp.fortran/associate4.f90: New test.
