[New-bugs-announce] [issue42891] segfault with gunicorn and a library made with cython bindings

[Amirouche Boubekki]

New submission from Amirouche Boubekki <amirouche.boubekki at gmail.com>:

Here is a simple way to reproduce:


from lsm import LSM


db = LSM('db.sqlite')

def app(environ, start_response):
    """Simplest possible application object"""

    for (index, (key, value)) in enumerate(db[b'\x00':b'\xFF']):
        pass

    start_response(b'200', {})
    return b''

db.close()


In my real program, if I add 'global db' in the function `app`, it does not segfault.
