Uh, yes it obviously is! The lambda is declared without any calling
conventions attributes, but the function pointer has them.

That has no meaning without defining your terms.

Are the tokens lexically analyzed twice?

Is the syntax parsed twice?

Or is the body of the lambda checked twice for type errors?

There is evidence that some code is generated twice.

If we have for (i = 0; i < N; i++) loop and we see four
copies of the body in the machine code, with a loop
index being incremented by 4, we don't say that
the loop body was compiled four times. There may have
been four copies of some intermediate code which got
code-generated four times.
