Bug#691989: clang: ICE when a class with multiple copy constructors is in a union

[Ben Longbons]

Package: clang
Version: 3.1-8
Severity: normal
Tags: upstream patch fixed-upstream

upstream bug url: http://llvm.org/bugs/show_bug.cgi?id=13480

Dear Maintainer,

The below code segfaults clang. This uses a C++11 feature that was not
implemented in clang 3.0, and it has been fixed in trunk for 3.2.

I am attaching a backported, slightly edited version of the patch.

// compile with -std=c++11
struct String
{
    String(const String&);
    String(String&);
};

union Impl
{
    String first;
};

*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

*** End of the template - remove these lines ***
