Possibly, but I'm unable to reproduce the crash: https://godbolt.org/z/Gsx9sWG4v

The value cached by KernelHandles in HIP is the the manually created 'Var' and not the function itself.  I don't think it ever changes outside of this function.

However, `KernelStubs` would still point to the original `F`, and that may potentially be left dangling. Perhaps I should always update both handles and stubs if `F` changes.
