cygmagic-1.dll - access violation by accessing the lib via python

["Holger Bast" <HolgerBast@gmx.de>]

Hi there,
I'm using a python wrapper (python-magic, https://github.com/ahupp/python-magic) checking some filetypes in a small script. The wrapper works fine under Unix-like system, but I got an access violation error under cygwin. I already tried an older version of file including libmagic from the gnuwin32-project and this one works fine - aside it's completely outdated ;)
This issue was already identified on the issue tracker of the python-wrapper but I don't think that this error is a problem of the wrapper  (see https://github.com/ahupp/python-magic/issues/76). I found some python wrappers on the cygwin mirrors (python-magic-5.24-1.tar.xz) but these also produce the same error.

Ok, here the script I used:

requirements: python 2.7 and python-magic

import magic

mage = magic.Magic(mime=True)
filetype = mage.from_file("testfile.odt")
print filetype


Output:

Traceback (most recent call last):
  File "C:/Users/aronadaal/PycharmProjects/libmagic-test/magictest.py", line 3, in <module>
    mage = magic.Magic(mime=True)
  File "C:\Python27\lib\site-packages\magic.py", line 59, in __init__
    self.cookie = magic_open(self.flags)
WindowsError: exception: access violation writing 0x0000000000000000
Exception AttributeError: "Magic instance has no attribute 'cookie'" in <bound method Magic.__del__ of <magic.Magic instance at 0x00000000022CEA48>> ignored

Notice: You can ignore the last message regarding the "cookie"-variable. The filehhandler is stored inside it during the initialization. That's ok.

Bye, aronadaal
