No i meant #PF because #PF can do it reliably (sorry wasn't fully
convinced by you earlier)

But ok doing it a little unreliably in #GP is better than nothing.

It would be cool if that function knew about the various poisons
in poison.h and printed them out by name.

That would indeed improve newbie friendliness of oopses significantly
I believe. Kind of like a mini AI in the oops printer.

I can look at that later if nobody beats me to it.
