RE: gcc 3.1: bug with inherited templates when specified by namespace

["Mountfort, Geoff" <gmountfort at avaya dot com>]

Dylan,

my previous reply suffered from "hit Send before thinking". The error refers
to line 13, which consists of the two words "template parameter?". Don't you
just love word wrap? Back to the original question ...

namespace SomeSpace
{
template< class T >
class Frog
{
    T   m_t;    // doesn't matter what's here
};

}


class MrBlobbyBlab : public SomeSpace::Frog
{
};

compiles. But

namespace SomeSpace
{
template< class T >
class Frog
{
    T   m_t;    // doesn't matter what's here
};

}

using namespace SomeSpace;
class MrBlobbyBlab : public Frog
{
};

doesn't compile, getting

Frog.cpp:13: parse error before `{' token

That's very strange - maybe my use of "other" conflicts with something ( I
think I simplified it to "other" for the example because I didn't think
there was any conflict), please could you try changing the namespace name
from other to something else.
