Tests fail on OS X

No idea where to start.

It's probably just something screwy with that particular test, which I just tossed together and haven't touched in a while. For now just comment out line 32 of tests.rs or just remove the test_events() function and I'll have a look at it sometime soon.

Edit: Comment out lines 32 and 33 that is.

[c0gent]

Just made that change on master.

Would be curious to know how things are working on OS X before I close this issue.

I'll try to take a look this weekend. Unfortunately I needed to use the OpenCL image APIs and I wasn't about to learn Rust and OpenCL while building out the OpenCL functions I needed in Rust- that's a bit of a steep learning curve.

Ended up going with this golang lib unfortunately, it had the needed wrapper functions :-/

I'm about to add image support to this library, would appreciate another look in a few weeks and possibly some feedback.

[lattwood]

Looking forward to it.

Just pushed version 0.7. The new Image type has most of the basic stuff implemented. I'd like to maybe add some sort of mechanism so that different sized format channels and data_types provide some guidance on the type and size of vector needed to work with them but I'm not sure how much assistance is too much.

Having zero experience with OpenCL images myself, I'd really appreciate your feedback and even design ideas if you have any.

This may be related in that the error looks similar to one I get running the events example panics (on OS X with an Intel Iris Pro GPU). Here's the output:

@neverfox

Alright let's get to the bottom of it... Would you mind creating a new issue and just referencing this one?

[neverfox]

Sure thing, @c0gent.
