Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

The bug has different results every time. I think it happens more often when typing very quickly.

Thanks for the reporting the bug.

I think this is fixed in 7.2.1 and later (see #5588). Please re-open the ticket if you encounter the bug in a more recent version of GHC.
