There is a pragma in VC6 that will activate or deactivate optimization. It can be used to wrap optimization-sensitive blocks of code. I do not remember what it is, though, and I do not have VC6 handy. I have used it, and it did alleviate an optimization-related bug.

From the MSDN:

#pragma optimize( "[optimization-list]", {on | off} )

Specifies optimizations to be performed on a function-by-function basis. The optimize pragma must appear outside a function and takes effect at the first function defined after the pragma is seen. The on and off arguments turn options specified in the optimization-list on or off.

I'm curious, why couldn't this be a compiler workaround in weak_ptr?
