IOError: [Errno 9] Bad file descriptor when running shcov on Mac OSX

[GoogleCodeExporter]

What steps will reproduce the problem?
1. echo -e '#!/bin/bash\necho "Some test message"\n' > test.sh
2. chmod +x test.sh
3. ./shcov test.sh

What is the expected output? What do you see instead?
I expected to get 'Some test message'. What I got was that and a traceback.

What version of the product are you using? On what operating system?
commit 3c3e16a0b49eb4b695107f842b5d7b387b70e5ab
Mac OSX 10.6.8
Python 2.7.6

Please provide any additional information below.

The error doesn't seem to be file related, because if I give it a non-existent 
file is throws the same traceback. This works on a RHEL6 system I have 
elsewhere.

$ cat test.sh
#!/bin/bash
echo "Some test message"

$ ./shcov test.sh
Traceback (most recent call last):
  File "./shcov", line 176, in <module>
    out = sc.parse_output()
  File "./shcov", line 109, in parse_output
    self.process.stderr.flush()
IOError: [Errno 9] Bad file descriptor
Some test message

$ ./shcov jfdkls

$ ./shcov --help;
Usage: shcov [-h] [--output=where] [--shell=what] script...

Produce coverage data for 'script'. Options are

  --output=where  write data to 'where' instead of /tmp/shcov
  --shell=what    ues 'what' (including arguments) as shell instead of 'bash -x'
