> This patch adds a check when unboxing the target address of a native call to check that the address is not `NULL`. Additionally, it adds checks earlier when an address is specified with a linking request, to check that that address is not `NULL`.
> I didn't see any regressions on the CallOverhead* benchmarks.
> Thanks,
> Jorn
