[Boost-users] Boost.mpl metafunction with integral value problem

Hi,

I've been trying boost::mpl for my current project and
hit a problem.
Sorry if it is an already known issue. So if we have
our own
metafucntion:
template< typename T, typename Value > func :
mpl::void_ {};

it works fine:
typedef mpl::find_if< mpl::vector< int, char >, func<
mpl::_1,
mpl::int_< 10 > >::type iter;
...

But if I try to use integral value instead:
template< typename T, int Value > func : mpl::void_
{};

and

typedef mpl::find_if< mpl::vector< int, char >, func<
mpl::_1, 10

>::type iter;

It fails on gcc 3.3.3 nor 3.4.3.
So is it a limitation on language or compiler or
library? I mean should
second variant compile in generic?

Regards,
Vyacheslav
