ZeroInitialize( T& ) does not compile on LLVM 3.0 #539

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The bullet function:

template <typename T>
static inline void          ZeroInitialize(T& value)
{
        static const T  zerodummy;
    value=zerodummy;
}

is wrong according to Apple LLVM 3.0, that outputs the error "Default 
Initialization of an Object of const Type requires an User-Defined default 
Constructor" for various btSoftBody nested classes:
Tetra, Face, Link, Note, Material, Node.

I really think this should be correct C++, but it will stop compilation no 
matter what.

This is already fixed in the latest trunk:

template <typename T>
static inline void          ZeroInitialize(T& value)
{
    memset(&value,0,sizeof(T));
}

Thanks,
