compactAdd doesn't work with SmallArray#
I get this when I try to compact a small array:
internal error: stg_compactAddWorkerzh: TODO: SMALL_MUT_ARR_PTRS (GHC version 220.127.116.1170404 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
If I look in
rts/Compact.cmm, I can see that this hasn't been implemented. I haven't seen this in another issue, so I just wanted to make sure it was not overlooked before the 8.2 release.
