Memory leak with parMap
With the attached All.hs
, if you run the program without any arguments (so that it uses parMap rnf
in gen_blocks_list
) then its memory usage keeps going up, even though at the top level it's just running the same computation 5 times in a row. Memory usage goes up to over 100M.
If you give an argument (any argument, so that it uses map
instead) then memory usage is constant and only a few megs.
Happens in 6.8.2 and the HEAD.
