#include <vector>
struct S
{
int A;
std::string B;
};
struct V
{
std::vector<S> v;
};

But there seems to be no need for is_local_temp to check for function scope; !TREE_STATIC should be enough. PR c++/104182 gcc/cp/ChangeLog: * cp-gimplify.cc (cp_genericize_target_expr): Make sure nothing has set DECL_INITIAL on a TARGET_EXPR slot. * tree.cc (is_local_temp): Don't check DECL_CONTEXT. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/initlist127.C: New test. ^ permalink raw reply [flat|nested] 6+ messages in thread
