panic after pressing Ctrl+C in ghci

Hello! I'm using GHCi 7.0.3 on Windows 7.

I found the following easy reproducible bug:

  1. Start ghci
  2. Hit Ctrl+C.
  3. Type something, e.g. abc, press enter
  4. ghci will crash with the error:

ghc.exe: panic! (the 'impossible' happened)

(GHC version 7.0.3 for i386-unknown-mingw32):
