Summary: Regression in Template Constants from 4.5.2
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: swest...@gmail.com
The following code compiles cleanly under g++ 4.5.2, but fails to compile under
g++ 4.6.0:
#include <climits>
#include <boost/mpl/int.hpp>
boost::mpl::int_<INT_MIN> foo;
It produces the errors:
/usr/local/include/boost/mpl/aux_/integral_wrapper.hpp: In
instantiation of ‘mpl_::int_<-0x00000000080000000>’:
test_test.cpp:8:27: instantiated from here
/usr/local/include/boost/mpl/aux_/integral_wrapper.hpp:73:96: error:
‘2147483647’ is not a valid template argument for type ‘int’ because
it is a non-constant expression
/usr/local/include/boost/mpl/aux_/integral_wrapper.hpp:73:96: error:
overflow in constant expression [-fpermissive]
I tested this using Boost 1.46 on a Debian AMD_64 SID system running with a
2.6.36 kernel.
