Comment (by chak):

 @ezyang Thanks for chasing this, but I'm a bit surprised that the problem
 is with freeing stable names as the example program only allocated them
 (and they should never be freed by the GC).

 @robertce Could you please build a GHC with this patch included and check
 whether it solves our problem?
