If the lambda expression captures anything by copy (either implicitly with capture clause [=] or explicitly with a capture that does not include the character &, e.g. [a, b, c]), the closure type includes unname

Lambda capture this by value Capturing this in a lambda's environment was previously reference-only. An example of where this is problematic is asynchronous code using callbacks that require an object to be available, potentially past its lifetime. *this (C++17) will now make a copy of the ...

The migrated API does not return an error code. 0 is returned in the lambda. You may need to rewrite this code. DPCT1035 All SYCL devices can be used by the host to submit tasks. You may need to adjust this code. DPCT1036
