Bug ID: 114562 Summary: ICE when trying to bind rvalue reference to lvalue with comma operator and forwarding reference to pointer Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: liam.jack...@qa-systems.com Target Milestone: --- Created attachment 57846 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57846&action=edit Source to reproduce ice Compiling the attached source would expect to raise an error such as error: cannot bind rvalue reference of type 'const void*&&' to lvalue of type 'void* const' Instead the following ICE occurs: <source>: In instantiation of 'static T Create<T>::create(U&&) [with U = void* const&; T = MyClass]': <source>:34:28: required from here 34 | Create<MyClass>::create(MyClass::NONE); | ~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~ <source>:28:13: internal compiler error: in convert_like_internal, at cp/call.cc:8879 28 | return T( ( (beforeParam()), (u) ) ); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 0x266d8bc internal_error(char const*, ...) ???:0 0xa572eb fancy_abort(char const*, int, char const*) ???:0 0xa81334 build_new_method_call(tree_node*, tree_node*, vec<tree_node*, va_gc, vl_embed>**, tree_node*, int, tree_node**, int) ???:0 0xa8265b build_special_member_call(tree_node*, tree_node*, vec<tree_node*, va_gc, vl_embed>**, tree_node*, int, int) ???:0 0xa8ff69 perform_direct_initialization_if_possible(tree_node*, tree_node*, bool, int) ???:0 0xd33f73 build_functional_cast(unsigned int, tree_node*, tree_node*, int) ???:0 0xc92ed3 instantiate_decl(tree_node*, bool, bool) ???:0 0xcbc0ab instantiate_pending_templates(int) ???:0 0xb5a619 c_parse_final_cleanups() ???:0 0xdaf328 c_common_parse_file() ???:0 It may be possible to construct an example source which is expected to compile successfully yet still triggers this ICE. This has not been explored.
