Access Violation with ImageMagick 7.1.0-62/6.9.12-77

[JayBraker]

I'm experiencing a similar issue to #586 when attempting to instanciate wand.image.Image:

Type "help", "copyright", "credits" or "license" for more information.
>>> from wand.image import Image
>>> from pathlib import Path     
>>> Image(filename=Path('.\in\123456_u.pdf').absolute)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\User\AppData\Roaming\Python\Python310\site-packages\wand\image.py", line 9053, in __init__
    wand = library.NewMagickWand()
OSError: exception: access violation writing 0x0000000000000008
>>>

I'm running Python 3.10.8 64bit with ImageMagick 7.1.0-62
The issue also occurs with ImageMagick 6.9.12-77 (both 64bit, installed with dev headers)

@emcconville 's workaround works fine:

Type "help", "copyright", "credits" or "license" for more information.
>>> from pathlib import Path     
>>> from wand.image import Image                                              
>>> from wand.resource import genesis as wand_genesis  
>>> wand_genesis()
>>> Image(filename=Path('.\\in\\123456_u.pdf').absolute(), resolution=150) 
<wand.image.Image: ec37aa8 'PDF' (1240x1754)>
>>>

Ensure you have the latest version of Wand. This issue should have been fixed last year, and I'm unable to reproduce issue with latest versions of ImageMagick.

Just to confirm this, I had and 0.6.7 installed with ImageMagick-7.1.1-4-Q16-HDRI-x64 on Windows and was getting the above error. Upgrading to wand 0.6.11 solved it.

Cool. Thanks for confirming this. Closing.
