Created attachment 20172 [details] test case If I switch the comments on lines 27-28 the code compiles, i.e. it is the GENERIC interface that is not resolved correctly.
Forgot to highlight that this only applies to fortran-dev branch, with a fresh 4.5 build it compiles cleanly.
Confirmed.

Here is a preliminary patch: Index: gcc/fortran/resolve.c =================================================================== --- gcc/fortran/resolve.c (revision 158513) +++ gcc/fortran/resolve.c (working copy) @@ -5174,7 +5174,7 @@ resolve_typebound_generic_call (gfc_expr* e, const /* Pass along the name for CLASS methods, where the vtab procedure pointer component has to be referenced. */ if (name) - *name = target->name; + *name = g->specific_st->name; goto success; } } It fixes the test case, but I haven't regtested it yet.

Not only does it regtest but I had a few minutes to commit it in your name, as obvious! Thanks for the fix, Janus, and thanks for the report, Salvatore. Paul
