           Summary: parse error when using a typedef for a static member
                    variable of a template
           Product: clang
           Version: trunk
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: juergen.hunold at ivembh.de
                CC: llvmbugs at cs.uiuc.edu


Consider the following code:

namespace First
{
    template<class T>
    class Bar
    {
    protected:

        static const bool static_bool;
    };
}

namespace Second
{
    class Foo;
}

typedef First::Bar<Second::Foo> Special;

namespace
First
{
    template<>
    const bool Special::static_bool(false);
}

clang -v
clang version 3.0 (trunk 129243)
Target: x86_64-unknown-linux-gnu
Thread model: posix

a.cpp:22:5: error: extraneous 'template<>' in declaration of variable
'static_bool'
    template<>
    ^~~~~~~~~~
1 error generated.

This examples compiles with gcc-4.3 up to 4.6 and at least msvc-9.0
Clang compiled it fine, but this broke a week (or so) before the branch for 2.9
