Hi Alexey,

Yes, it will be handled correctly. The map clause doesn't change the way codegen is done for the host. The host always takes the original references regardless the map clause and its modifiers. Even for the device side, map clause won't have any effect in the code generation of the outlined target function. This behavior is what ensures that everything works seamlessly in a system that has a shared address space for host and device.

In any case, I added a new regression tests (CK25) that ensures that the lambda gets the same captures regardless the map clause.
