Can't save JPEG2000 to a BytesIO object

[CSNE]

What did you do?

I tried to save a JPEG2000 image into a BytesIO object.

What did you expect to happen?

It should have saved the image file into the BytesIO object.

What actually happened?

The script fails("python.exe has stopped working").

What versions of Pillow and Python are you using?

Python 3.3.4 (32-bit) and Pillow 3.2.0
I also tried using Python 3.5.1, but the script still fails.

from PIL import Image
from io import BytesIO

#Any image will reproduce the bug.
img=Image.open(r"some-image.png")

print("Saving ordinary JPEG to a BytesIO object. This works fine.")
bio=BytesIO()
img.save(bio,"JPEG")

print("Saving JPEG2000 to a file. This also works fine.")
img.save(r"some-other-image.jpf","JPEG2000")

print("Saving JPEG2000 to a BytesIO object. This fails.")
bio2=BytesIO()
img.save(bio2,"JPEG2000")

Is this Windows? And is it a crash or a exception?

[CSNE]

I'm using Windows 8.1.
When I run the script, no traceback is printed in the console, but a Windows dialog pops up saying "python.exe has stopped working.". So I guess it's a crash.

That's a crash, and it's odd. Our roundtrip tests for J2k use bytesio, so that should be the most well tested configuration. On the other hand, we don't have that configuration in ci, so it's possible something is wrong.

Update: Just tried running the script on two of my friend's computers(one Windows 7 w/ Python 3.5 and one Windows 8.1 w/ Python 3.5). They don't crash.
Perhaps it was just my machine.

It does seem that way. You could have some corruption in the pillow or the python install which might be fixed by reinstalling.

Reinstalling doesn't help, might be something wrong in the system.
Anyways, thanks!
