Summary: [C++0x] Another incomplete type regression with
noexcept
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: marc.glisse@normalesup.org
This is another case of noexcept specifications causing instanciations and
resulting in incomplete types (see PR c++/49107 for the first one). Reporting
against C++ instead of libstdc++ like 49107.
