Image causing segmentation fault

[Joelgranados]

This image causes segmentation fault

[Joelgranados]

The image is corrupted in some way, and should just be ignored. Instead it causes a seg fault. Not sure where and not sure in what component.

Try running:

import skimage.io
skimage.io.imread("image", plugin="freeimage")

If that segfaults, then it's the bug I found a while ago. If so, pip install from scikit image's master git branch.

Cheers, K

I just did a pip install git+https://github.com/scikit-image/scikit-image.git@master and the segmentation fault still persisists. Can you confirm that you fix addesses this issue? What happens when you run skimage.io.imread("image", plugin="freeimage") Notice that I made sure that your e63ae9450ac7b236e5dcbf859d8fc7f8741bf304 in skimage was present in my install.

OK, that's a new bug then. Will investigate tomorrow, but my fix to skimage definitely fixed the old bug.

Where is that image on phenocam?

Also, can you send a gdb backtrace? Thanks

(P.S., remember to wrap the backtrace in triple backquotes if you paste it in here, or it will reference all issues, as the stack level indicator lines start with # followed by the backtrace depth.)

Image is the one I uploaded to this bug. The way to reproduce it is the three line code snipped that you posted previously. Here goes the backtrace:
