ghc.exe: panic! (the 'impossible' happened)
(GHC version 7.6.3 for i386-unknown-mingw32):
thread blocked indefinitely in an MVar operation
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
"
I am able to reproduce it by:
1. starting ghci (with no arguments, or a file as an argument)
2. holding down contol-c for 2 seconds
3. holding down spacebar/a letter key for 2 seconds
The timing varies.
