Re: [Boost-users] C++03 unique_ptr emulation

Would probably specifying the /Zm2000 compiler help? Can't test it right now. This is the precompiled header memory size, but I found it to be helpful even in non-precompiled header projects/files. With Kind Regards, Ovanes On Fri, Mar 6, 2009 at 3:30 PM, Sergey Skorokhodov wrote:

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. 1>(compiler file 'f:\dd\vctools\compiler\utc\src\p2\ehexcept.c', line 1454) 1> To work around this problem, try simplifying or changing the program near the locations listed above. 1>Please choose the Technical Support command on the Visual C++ 1> Help menu, or open the Technical Support help file for more information 1>Build log was saved at "file://c:\prj\VS2005\Projects\unique_tsts\unique_tst\Debug\BuildLog.htm" 1>unique_tst - 1 error(s), 0 warning(s)

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

TIA
