We are now more strict when accepting user-defined initializer_lists; in particular, we now require sizetype, not just any integral type. The following test failed with -m32, because it had a bogus type of size_t, with -m32 it usually should be unsigned int, not unsigned long.
Test passes now with both -m32/-m64, ok for trunk? 2015-04-02 Marek Polacek <pola...@redhat.com> * g++.dg/cpp0x/pr57101.C: Use proper type for size_t. diff --git gcc/testsuite/g++.dg/cpp0x/pr57101.C gcc/testsuite/g++.dg/cpp0x/pr57101.C index 94b576f..c0fc966 100644 --- gcc/testsuite/g++.dg/cpp0x/pr57101.C +++ gcc/testsuite/g++.dg/cpp0x/pr57101.C @@ -1,7 +1,7 @@ // { dg-do compile { target c++11 } } // { dg-options "-fcompare-debug" } -typedef long unsigned size_t; +typedef __SIZE_TYPE__ size_t; namespace { template < typename _Tp, _Tp __v > struct integral_constant Marek
