Bug ID: 77658
Summary: internal compiler error: in assign_temp, at
function.c:961
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: naupacte at sfr dot fr
Target Milestone: ---
//A very strange combination is needed to produce the ICE:
//Full program:
struct A
{
// A();
~A(); // NEEDED to produce ICE
};
#ifdef FIRST_CASE
A a (int) { throw ""; return {};}
A b (int) { throw ""; return {};}
A c (int) { throw ""; return {};}
A d (int) { throw ""; return {};}
A e (int) { throw ""; return {};}
#else // second case
A a (int) { throw 1;}
A b (int) { throw 1;}
A c (int) { throw 1;}
A d (int) { throw 1;}
A e (int) { throw 1;}
#endif
//EOF
NB: THERE MUST be at least 5 such functions:
- returning type A
- and throwing same type
- having one (unique?) same argument type
