Shouldn't that be
char *strcpy(char * const p, size_t __size_of_p, const char * const
q, size_t __size_of_q)
? i.e. the docs point at this but say:
"...and implicitly pass the result of this call in as an invisible
argument of type `size_t` directly after the parameter annotated with
`pass_object_size`."
Cheers,
Miguel
