> Lazy Exceptions are not implemented on x86-64 platforms.
> On both Windows and Linux x85-64 platforms Lazy Exceptions are not implemented. The main
issue, which privets implementation, is register calling conventions on both these platforms.
On x86-32 Lazy Exception helpers works by following scenario: lazy exception helper founds
quantity of parameters for exception constructor and just sent corresponding address to stack
as arguments array in the next functions stack. To implement this feature on x86-64 platforms
function, which converts parameters from registers to array, should be implemented.
