Hi,

thanks for your response.

Yes it always segfault:

$ ./python -c 'import os; print(os.fdlistdir(os.open("/tmp", os.O_RDONLY)))'
zsh: segmentation fault (core dumped)  ./python -c 'import os; print(os.fdlistdir(os.open("/tmp", os.O_RDONLY)))'

$ ./python -c 'import os; print(os.fdlistdir(os.open("/tmp/test_python", os.O_RDONLY)))'
zsh: segmentation fault (core dumped)  ./python -c 

$ ./python -c 'import os; print(os.fdlistdir(os.open("/var/tmp", os.O_RDONLY)))'
zsh: segmentation fault (core dumped)  ./python -c 'import os; print(os.fdlistdir(os.open("/var/tmp", os.O_RDONLY)))

With listdir it correctly works:

$ ./python -c 'import os; print(os.listdir("/tmp"))'                          
['.X11-unix', '.ICE-unix', 'test_python', 'tmpl80ewt', 'tmpled292']

$ ./python -c 'import os; print(os.listdir("/tmp/test_python/"))'
['1file', '2file', '3file']

$ ./python -c 'import os; print(os.listdir("/var/tmp/"))'
