Here is the test case:

#pragma managed(push, off)
#include <list>

class C3821
{
     std::list<int*>* p;

public:
     C3821( size_t n )
            : p(new std::list<int*>[n])
     {
     }
};
#pragma managed(pop)

I've been able to verify that it works in VS2005 SP1 but not in VS2008 SP1,
appreciate anyone who can check it on RTM versions or has VS2010 beta handy.

VS 2010 output:

1>ClCompile:
1> c3821.cpp

So you have to use #pragma unmanaged, which also happens to be in effect, so
the error is obvious, right? (And yes, this is verbatim output, it's
"functon" -- well, it's a beta.)
