Description

The following code results in an Illegal Instruction (SIG 4):

cv2.imread('pd_bmw_e92_widebody_front-side_view_1_300dpi_cmyk_6.jpg', cv2.CV_LOAD_IMAGE_GRAYSCALE)

I'm running OpenCV 2.3.1 from this repo (https://launchpad.net/~gijzelaar/+archive/opencv2.3), on Ubuntu 11.04 with all the latest packages. This is being run on a Rackspace virtual machine, and I suspect that that is part of the problem, as I can't reproduce this on my development machine (a Penryn CPU, running Ubuntu 11.10).

Let me know if you need any further details. I have attached the offending image.

Another note. My code has run fine on thousands of other images, so there seems to be something about this one in particular.

I can not reproduce this problem either. On the virtual machine, try to build OpenCV from sources, may be, it will work that way.

Yep, compiling from source seems to have fixed it. Thanks!

ok, then I'm closing the ticket, since the problem is in the ubuntu packages, not OpenCV itself.
