Comment:

 Thanks for the report. In fact "getptrval = liftM2 lift" is enough to
 trigger panic in GHC 7.6. This is fixed in the development version (bugs
 #7368, #7441).

 [You might have wanted something like `liftM2 (\a b -> lift (readArray a
 b)) (gets mem) (gets ptr)` but I did not check whether that works.]
