 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):
         thread blocked indefinitely in an MVar operation

 Regards,
 Matthias Böhm
