#3112: GHCI Crashes on self referential local variable

{{{
f :: Int -> Int
f x =
let p = x*x
in
let p = p*x
in p
}}}
Causes a segfault of GHCI on Windows XP Service Pack 2, and unbounded
memory consumption on Linux. There is no output when the crash occurs,
after invoking the function (for example f 7) it just immediately drops
back to a command prompt in Windows. I would expect some sort of error
message to be printed, perhaps <loop>, and then return gracefully to the
GHCI prompt.
