Description

When using a lambda as a deleter for std::unique_ptr, the unique_ptr ceases to cast to a bool correctly. The provided sample code compiles correctly in Visual Studio 2010, but fails to compile in Visual Studio 2012.

Hi,

Thanks for reporting this bug. We've fixed it, and the fix will be available in VC12. (Note: VC8 = VS 2005, VC9 = VS 2008, VC10 = VS 2010, VC11 = VS 2012.)

We've implemented explicit operator bool() throughout the STL, which is immune to this bug that affected operator fake-bool().

Note: Connect doesn't notify me about comments. If you have any further questions, please E-mail me.
