 The following program crashes when I try to write a byte string larger
 than 61kb to stdout:

 {{{#!hs
 import qualified Data.ByteString.Char8 as BS

 main = BS.putStrLn $ BS.replicate (62 * 1024) 'x'
 }}}

 When I run the above, I get the following runtime error:
 {{{
 <stdout>: hPutBuf: resource exhausted (Not enough space)
 }}}

 GHC versions tested: 7.6.3 and 7.8.3 (both 32 and 64 bit)
 OS: Windows 7 and Windows Server 20008R2

 The issue is not reproducible with the Linux version of GHC. It is also
 not reproducible if I use the Lazy variant of the byte strings.

 Note: The Linux version of the program was tested with GHC 7.6.3 because
 this is the one I have on my Ubuntu machine.
