It works with 3.2.2. Kriang, I'm CCing you because it might be related to the other segfault you fixed in convert_nontype_argument (it's still a SCOPE_REF with no type computed). -- Summary: [3.4/3.5 Regression] Segfault in convert_nontype_argument with invalid pointer to member Product: gcc Version: 3.5.0 Status: UNCONFIRMED Keywords: ice-on-invalid-code Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: giovannibajo at libero dot it CC: gcc-bugs at gcc dot gnu dot org,lerdsuwa at users dot sourceforge dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13929 ^ permalink raw reply [flat|nested] 4+ messages in thread

I think this is also fixed on the 3.4.0 branch but I did not test it. I almost think it was fixed by: 2004-01-26 Mark Mitchell <mark@codesourcery.com> * class.c (add_method): Just check processing_template_decl to determine whether or not we are within a template. * decl2.c (maybe_retrofit_in_chrg): Likewise. * init.c (decl_constant_value): Check the type of the declaration, not TREE_READONLY. * name-lookup.c (maybe_push_to_top_level): Rename to ... (push_to_top_level): ... this. * name-lookup.h (maybe_push_to_top_level): Do not declare it. * pt.c (push_template_decl_real): Reorder condition for speed. (convert_template_argument): Use dependency-checking functions in place of uses_template_parms. (lookup_template_class): Avoid calling uses_template_parms more than once. (uses_template_parms): Reimplement, using dependency-checking functions. (instantiate_class_template): Use push_to_top_level, not maybe_push_to_top_level. (type_unification_real): Simplify. (type_dependent_expression_p): Handle OFFSET_REFs and TEMPLATE_DECLs. (any_dependent_template_arguments_p): Handle multiple levels of template argument. * semantics.c (expand_or_defer_fn): Do not check uses_template_parms for template instantiations. * typeck.c (comptypes): Avoid calling cp_type_quals. -- What |Removed |Added ---------------------------------------------------------------------------- Summary|[3.4/3.5 Regression] |[3.4 Regression] Segfault in |Segfault in |convert_nontype_argument |convert_nontype_argument |with invalid pointer to |with invalid pointer to |member |member | Target Milestone|--- |3.4.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13929 ^ permalink raw reply [flat|nested] 4+ messages in thread
