Bug #: 57153
Summary: [C++11] tries to use copy constructor for in-class
initialized member in default constructor of template
struct
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: f.heckenbach@fh-soft.de
Created attachment 30014
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30014
Test case
The included test case produces the following error:
% g++-4.7 -std=c++11 test.cpp
test.cpp: In constructor 'constexpr B<0>::B()':
test.cpp:8:8: error: use of deleted function 'A::A(const A&)'
test.cpp:4:3: error: declared here
test.cpp: In function 'int main()':
test.cpp:17:9: note: synthesized method 'constexpr B<0>::B()' first required
here
I don't think a copy constructor of the member should be needed for the default
constructor of the containing struct.
The error disappears when I declare the latter explicitly, but not when I
declare it as "= default".
Is also disappears if struct B is not a template. I don't see why this should
make a difference.

I agree that the code should be accepted, because the member initializer
performs direct-initialization. The very same problem also exists for gcc 4.9.0
20130428 (experimental).
