Bug ID: 80984
Summary: [5/6/7/8 Regression] ICE with label/variable ambiguity
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org

};
A foo()
{
A a;
a:
return a;
}
===================================
bug.cc: In function 'A foo()':

parm_decl or result_decl, have label_decl in cp_genericize, at
cp/cp-gimplify.c:1594
}
