Summary: missing 'typename' in debug-mode map
Product: gcc
Version: 4.3.5
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
include/debug/map.h refers to a type in a dependent base class, without using
'typename'
using _Base::value_compare;
I'm not sure if this is actually *wrong* - EDG accepts it too, as long as we
don't try to use value_compare in that scope without adding 'typename' (and we
don't do that.)
However, clang++ rejects it, so debug mode maps cannot be used with clang:
/opt/gcc/include/c++/4.4.3/debug/map.h:72:20: error: dependent using
declaration resolved to type without 'typename'
using _Base::value_compare;
^
adding 'typename' allows debug/map.h to be used with clang++, and doesn't seem
to fall foul of PR 14258 (again, because we don't actually use the type in that
scope)
Another fix would be
typedef typename _Base::value_compare value_compare;
present in all active releases, not a regression
same problem exists in include/debug/multimap.h
