 Hi,

 I'm trying to generate a heap profile via "+RTS -hb" on macOS 10.13.4.
 Unfortunately I get the following error:

 `internal error: Invalid object in processHeapClosureForDead(): 7`\\
 `(GHC version 8.2.2 for x86_64_apple_darwin)`\\
 `Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug`\\
 `Abort trap: 6`

 Best regards

 Doro
