The following invalid testcase triggers an ICE on mainline: ========================================= template<void> struct A { A(); virtual ~A(); };
A<0> a; ========================================= bug.cc:1: error: 'void' is not a valid type for a template constant parameter bug.cc:3: error: templates may not be 'virtual' bug.cc: In instantiation of 'A<<expression error> >': bug.cc:7: instantiated from here bug.cc:3: internal compiler error: in finish_member_declaration, at cp/semantics.c:2243 Please submit a full bug report, [etc.] If I remove the constructor or destructor, the ICE happens in the same place as PR 24791. This is probably fallout from PR 27668. -- Summary: [4.2 regression] ICE with virtual destructor in invalid template class Product: gcc Version: 4.2.0 Status: UNCONFIRMED Keywords: ice-on-invalid-code, error-recovery, monitored Severity: minor Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: reichelt at gcc dot gnu dot org BugsThisDependsOn: 27668 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28742
