Yeah, you have to watch out for the stack depth when CATCH returns
through THROW. It restores it to the original depth (minus the XT
that you executed). So you still have space on the stack from
`this`. But the actual values are arbitrary -- it depends on what
the intervening code has done to the stack before the THROW.

So for instance:

: a -2700 throw ;
: b 12345 67890 11111 33333 ['] a catch ;
b .s cr
