The following invalid code snippet is triggers an ICE since GCC 4.3.0: ======================================== template<typename... T> int foo(int i) { return *reinterpret_cast<T*>(i); }
void bar(int i) { foo<int>(i); } ======================================== bug.cc: In function 'int foo(int) [with T = int]': bug.cc:8: instantiated from here bug.cc:3: internal compiler error: tree check: expected record_type or union_type or qual_union_type, have template_type_parm in lookup_conversions, at cp/search.c:2459 Please submit a full bug report, [etc.] It's a regression because the code crashes even without -std=gnu++0x. -- Summary: [4.3/4.4 regression] ICE with reinterpret_cast and variadic templates Product: gcc Version: 4.4.0 Status: UNCONFIRMED Keywords: ice-on-invalid-code, monitored Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: reichelt at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38795
