Hello,
I'm having a little weird situation here.
Whenever I call exitFailure under forkProcess, I get:
(progname): forkProcess: uncaught exception
Test program:
import System.Exit
import System.Posix.Process
main = forkProcess exitFailure
If you remove the forkProcess call, the program properly silently exits
with exit code 1.
I have no idea why it is displaying this message to stderr when called
under forkProcess. I argue that it shouldn't. It is perfectly valid to
return with an error code from a child process, and absolutely necessary
in some cases when your later waitpid() call needs to know what
happened. (Or, in Haskell, getProcessStatus()).
Thoughts?
