Description Olivier Goffart 2013-03-07 21:42:07 UTC 
This code is accepted by clang.

 struct bug { int a; int *b = [&]{ return &a; }(); };

But GCC (4.7 and trunk) report a compilation error:

error: invalid use of non-static data member ‘bug::a’
 struct bug { int a; int *b = [&]{ return &a; }(); };
                  ^
error: from this location
 struct bug { int a; int *b = [&]{ return &a; }(); };
                                           ^


calling this->a  works.

Confirmed.

This got fixed by today's commits. I'm adding the testcase and closing the PR.
