Invalid object in processHeapClosureForDead(): 2130762223

I just tried using -hb profiling for Yi and hit

yi: internal error: Invalid object in processHeapClosureForDead(): 2130762223
    (GHC version 7.8.3 for x86_64_unknown_linux)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
Aborted

Unfortunately I don't have an easy way to replicate. In my case it's to check out HEAD version of Yi, build with profiling and run

[nix-shell:~/programming/yi/yi]$ TERM=xterm yi_datadir=. dist/build/yi/yi -fpango --as=emacs -y /tmp /tmp/long +RTS -p -hb

where /tmp/long here is just a file with 1MB of the letter A repeated on a single line.
