Confirmed for GHC 7.0.2. Works fine in GHCi, but compiling it (in my 
case, with -O) and running the executable causes a stack overflow unless 
I run it with +RTS -K16m, and even then it spends 90% of its time in GC. 
This looks like it is probably a bug, to me. Maybe it should be reported 
in GHC's Trac?
