---------------------------+------------------------------------------------
 When very simple programs are compiled using the -feager-blackholing and
 -threaded flags in GHC 7.4.1 on Windows 7 and XP a segmentation fault
 frequently occurs during execution. This happens in programs that read a
 line from the keyboard and print a response. The problem occurs running
 the executable file directly, through ghci, and through runghc.

 The problem is resolved by compiling without the -feager-blackholing flag.
