The association between kernel and struct is done by symbol name. This doesn't work robustly for anonymous kernels as shown by the modified test case. An alternative association between function and struct can be constructed if necessary, probably though metadata, but on the basis that we currently miscompile anonymous kernels and that they are difficult to construct from application code and difficult to call from the runtime, this patch makes it a fatal error for now.
