Hi,

I've put up a new version of an C++03 emulated unique_ptr here:

<skip>

I tried to use this implementation with MSVC 7.1 sp1 and 9.0 sp1 and encounter ICE in the following code:

<code>

#include <cstdlib>
#include <string>
#include "unique_ptr.hpp"

class Base
{
protected:
explicit Base( std::string const & src )
{
target.reset( new char[src.length() + 1] );
memcpy( target.get(), src.c_str(), src.length() );
target[src.length()] = '0';
}

explicit Base( boost::unique_ptr<char[]> src )
: target( move(src) )
{}
virtual ~Base() {}

private:
boost::unique_ptr<char[]> target;
};

class Derived : public Base
{
public:
explicit Derived( std::string const & src ) : Base( src ) {}
explicit Derived( boost::unique_ptr<char[]> src )
: Base( move( src ) ) {}
virtual ~Derived() {}
};

int main(int argc, char * argv[])
{
char const TEXT[] = "This is a text";
boost::unique_ptr<char[]> ptxt( new char[sizeof(TEXT)] );
Derived drv( move( ptxt ) );
return 0;
}

</code>

Here is the exact compiler output:

1>c:\prj\vs2005\projects\unique_tsts\unique_tst\unique_tst.cpp(21) : fatal error C1001: An internal error has occurred in the compiler.
1>(compiler file 'f:\dd\vctools\compiler\utc\src\p2\ehexcept.c', line 1454)

1>unique_tst - 1 error(s), 0 warning(s)

Is something wrong with my code or is it a "pure" MSVC bug?

TIA
