Bug #: 57047
Summary: [C++11] stl_pair.h:137:64: internal compiler error:
Segmentation fault in constexpr constructor
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mattyclark...@gmail.com
template<class _U1, class _U2, class = typename
enable_if<__and_<is_convertible<_U1, _T1>,
is_convertible<_U2, _T2>>::value>::type>
constexpr pair(_U1&& __x, _U2&& __y)
: first(std::forward<_U1>(__x)), second(std::forward<_U2>(__y)) { }
Fails for my program when compiled with the following command line:
/usr/lib64/ccache/g++ -m64 -std=c++11 -Wall -Wextra -pedantic -pthread -flto
-DNDEBUG -O3 -Werror -pedantic-errors -fvisibility=hidden
