hPutBuf crashes when trying to write a large string to stdout (resource exhausted)

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

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.

changed weight to 5

added Tbug Trac import core libraries labels

After googling around, it seems that this is not an issue of hPutBuf per se, but probably a limitation of the Windows API call that it uses to print to the console. See this issue in a Python bug tracker. The reported symptoms are exactly the same:
