The 'Impossible' Happened, thread blocked indefinitely in an MVar operation
Unable to reproduce but... Windows 7 64bit GHCi 7.0.4 gcc 4.6.1
While experimenting with displaying infinite lists (working in prompt), holding arrow key to alter a previously entered statement, received the message ghc.exe: panic! (the 'impossible' happened)
(GHC version 7.0.4 for i386-unknown-mingw32):
thread blocked indefinitely in an MVar operation
(Great error message btw)
