New description:

 I have this program
 {{{#!hs
 main = print $ do x <- [ 0 .. 5 ] ; let { y = 5 - y } ; return y
 }}}
 I compile with `ghc-6.10.1 --make`

 and I execute with `+RTS -M10m -K10m`

 but still the executable quickly eats up all my memory.

 (I know the program is silly but still it should crash
 gracefully.)

 When I do the same thing with ghc-6.8.3,
 I get "Heap exhausted", as it should be.

Comment (by bgamari):

 Sounds like a bug to me, but it's not the bug covered by this ticket.
 Let's open a new ticket.
