Confirmed.

(gdb) l symbol.c:4278
4273
4274    void
4275    gfc_enforce_clean_symbol_state(void)
4276    {
4277      enforce_single_undo_checkpoint ();
4278      gcc_assert (latest_undo_chgset->syms.is_empty ());
4279    }

For some reason we fail to clean up when the function is contained in a module.
