Could you explain what you think the bug is?
My first reaction is that this is not a bug. #pragma poison works on
identifiers, no matter what context they appear in (outside of system
headers). For this reason, poison is not always useful.
__attribute__((deprecated)) might be closer to what you want, though
it can be hard to use that with system-declared functions like malloc.
