--- Comment #4 from janus at gcc dot gnu.org 2012-11-26 17:08:20 UTC --- Note: The same behavior occurs with all gfortran versions I tried (4.3, 4.6, 4.7 and trunk). The check which rejects it is in gfc_verify_binding_labels (resolve.c). It was committed with the inital ISO_C_BINDING patch: http://gcc.gnu.org/viewcvs?view=revision&revision=126185 This commit also includes a test case which is basically equivalent to the one in comment 3 (i.e. two interfaces binding to the same label): http://gcc.gnu.org/viewcvs/trunk/gcc/testsuite/gfortran.dg/binding_label_tests_3.f03?view=markup So it seems that this error is indeed triggered on purpose and not by accident. It may well be that ifort just fails to detect this error (ifort is not exactly known for good diagnostics). Have you checked other compilers?
