-----------------------------+----------------------------------------------
The code below segfaults on a variety of platforms and GHC versions - I've
tried 7.4.1 and 7.6.1, on Windows and Linux.
It seems to be related to (a) the specific choice of UTF8 - doesn't happen
with UTF16 or UTF32 etc and (b) having the invalid byte sequence at the
end of the thing being decoded.
{{{
import qualified Data.ByteString as B
import System.IO
tempFile = "temp"
main = do
utf8Ignore <- mkTextEncoding "UTF8//IGNORE"
B.writeFile tempFile (B.pack [128])
h <- openFile tempFile ReadMode
hSetEncoding h utf8Ignore
hGetContents h >>= putStrLn
}}}
