Summary: [8 Regression] ICE on valid code
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org

Target Milestone: ---
It's isolated from boost and it started with r253266:
$ cat ice7.ii
class a
{
};
template <class> class b
{
b (b &&c) : e (static_cast<a &&> (c.e)) {}
a e;
};
$ g++ ice7.ii -c
ice7.ii: In constructor ‘b< <template-parameter-1-1> >::b(b<
<template-parameter-1-1> >&&)’:
ice7.ii:6:40: internal compiler error: tree check: expected tree that contains
‘decl common’ structure, have ‘identifier_node’ in get_inner_reference, at
expr.c:7002
b (b &&c) : e (static_cast<a &&> (c.e)) {}
