Bug ID: 59665
Summary: User code can cause ambiguous references to "std" in
libstdc++
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: fanael4 at gmail dot com
The following PURE EVIL but legal code:
namespace foo { namespace std {} }
using namespace foo;
#include <algorithm>
causes the compiler to spew out lots of "error: reference to 'std' is
ambiguous" errors deep in the bowels of libstdc++, for rather obvious reasons.
Granted, this is code is worse than reload, but it's legal, and as such
shouldn't break the standard library.
