thumbnail just quits

[ingoogni]

What did you do?

C:\Users\ingo\Documents\Python\PostCamera\static\img\archive>python
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import PIL
>>> PIL.__version__
'6.0.0.post0'
>>> from PIL import Image
>>> image = Image.open('a.jpg')
>>> image.thumbnail((100,100))

C:\Users\ingo\Documents\Python\PostCamera\static\img\archive>

EDIT: actually applying any form of filter to scale has the same result
image.scale((100,100), Image.SomeFilterHere)

What actually happened?

After using image.thumbnail python just quits.

What are your OS, Python and Pillow versions?

• OS: win10
• Python: 3.7
• Pillow: 6 (Gohlke compile)

Can't reproduce. Could you share a.jpg and CPU details?

[ingoogni]

CPU AMD Phenom II X6 1045ST, every image fails, jpg's are uploaded to a server from phones.
After your question I tested on a laptop Intel i7-3520M and there it works fine. (python 3.7.4 win10)

CPU AMD Phenom II X6 1045ST

That CPU does not seem to have SSE4.1 and SSE4.2 instruction sets, just SSE4a.

Ah, just saw SSE4 and thought lets go, wasn't aware of the 'a' and that it makes a difference. Thanks. And thanks for all your compilations of python packages!
