wine 5.19 (5.18 is ok) hangs while running the following script in Python
(3.8.6)
the script runs the echo command, grabs the output and waits for termination

import subprocess
proc = subprocess.Popen('echo hello', shell=True, stdout=subprocess.PIPE)
stdout_data, stderr_data = proc.communicate()
ret = proc.poll()
print(ret, stdout_data, stderr_data)
