Redirect the output to a file?

I had Redirect the stdout and stderr like
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, bufsize=0, cwd=cmd_path, preexec_fn=os.setsid),
and write to a file. However, I got something has wrong order, like

=== Uncaught Python exception: ===

For some reason, I can't redirect stdout and stderr separately. If there Atheris has a parameter to save the crash log or do this by itself as well as crash sample?Thanks!
