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 src )
: target( move(src) )
{}
virtual ~Base() {}
private:
boost::unique_ptr target;
};
class Derived : public Base
{
public:
explicit Derived( std::string const & src ) : Base( src ) {}
explicit Derived( boost::unique_ptr src )
: Base( move( src ) ) {}
virtual ~Derived() {}
};
int main(int argc, char * argv[])
{
char const TEXT[] = "This is a text";
boost::unique_ptr 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.

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