waitForProcess fails with "Bad file descriptor"
I am running this small sample program:
int main() { return -1; }
from this Haskell code (both from ghci and compiled):
import System.Process
main = system "a.exe" >> putStrLn "This is not printed"
and get this error
tmp.exe: waitForProcess: invalid argument (Bad file descriptor)
I guess there is a runtime error inside system-call which crashes execution.
I am on Windows 7, ghc 6.12.1. I tried both Cygwin g++ and MSVS cl C++ compilers.
One side question: is there any other way to run external program?
