Hi!
Im porting my HsShellScript library to GHC-7.0.4 and to Cabal/Hackage.
It builds and installs fine:
~/src/hsshellscript-3.0.0 $ cabal clean

I've made a fine little test program src/test.hs:
import HsShellScript
main =
(outm "3\n1\n2\n")
-|- exec "/usr/bin/sort" ["-n"]
But this doesn't work. It generates a mysterious error message:
~/src/hsshellscript-3.0.0 $ src/test
test: <stderr>: hPutStr: illegal operation (handle is closed)
test: timer_settime: Invalid argument
"timer_settime" occurs only in the generated test binary. It doesn't occur
anywhere in the library or in "/usr/bin/sort":
~/src/hsshellscript-3.0.0 $ find -type f -print0|xargs -0 egrep timer_settime
Übereinstimmungen in Binärdatei ./src/test.
~/src/hsshellscript-3.0.0 $ egrep timer_settime /usr/bin/sort
(no output)
It looks like GHC has introduced this mysterous call of timer_settime. What
does that mean?
Thanks for any help,
Volker W.
