Re: [Haskell] rawSystem unpredictable with signals

When I hit Ctrl-C while the child process is running, sometimes:

1) rawSystem returns ExitSuccess

or

2) rawSystem raises an IOError saying the child terminated with a signal

I am totally at a loss as to explain this difference in behavior. I would prefer it to choose option #2 always.

Could process #1 have caught SIGINT while process #2 didn't? If so, GHC is not at fault, because wait() doesn't tell about caught signals. Udo. -- Lebensmittelskandal: Gene im Mais entdeckt! (angeblich eine Schlagzeile aus der BILD)
