System Information
Windows 7 64bits & GeForce GTX 460

Blender Version
Broken: 2.75a c27589e

Short description of error
Blender crashes when trying to display an OpenEXR Multilayer (created with the File Output Node)

Exact steps for others to reproduce the error

From the blend file I sent:

Render the image
Import it in the node editor (make sure you import the one created with the file output node)
Display a pass with the viewer node or with the composite with 'Render Result' selected in the UV/Image Editor
Crash

From a new file:

Switch to Cycles (There is no problem with Blender Internal)
Plug each of the output of the Render Layers in an input of the File Output Node
Set the File Output to OpenEXR Multi Layer
Render the image
Import it in the node editor (make sure you import the one created with the file output node)
Display a pass with the viewer node or with the composite with 'Render Result' selected in the UV/Image Editor

Notes

It doesn't crash with every pass (Passes like diffuse, glossy Transmission and subsurface crash, others don't)
It does not crash at all when the Alpha is not exported (though I get some weird results in passes like the Zdepth)
There is no problem when working with OpenEXR instead of OpenEXR Multipass
I have Included the blend file and the render

Could you try with the latest build from buildbot ?

I just tried and the problem is still there. Though for some reason the scene that I provided doesn't create a render that causes a crash (the provided image does).
Here is a new blend file with the bug
Bug_EXR_MultiLayer_02.blend
I tested with 7ae44e8 and the file has been created with this version as well.

I am having the same issue too. We made a lot of use in a recent project of the file output node and rendered the passes to OpenEXR MultiLayer. Not every output file crashed however, it was very hard to reproduce the error. However we were still able to do the compositing without problems by using Blender version 2.72 for Comp. That one never crashed.

Not sure if it is related to MultiView, I rather think it came up when the Compositor memory consumption improvements were merged to master. But that's partially guesswork.

Seems to be a multiview issue, goes to @dfelinto's desk!

There were some memory leaks which got fixed recently, could you please try again?

I just tried with 32157d8
This time it crashes as soon as I add the image in the node editor

@Muream the fix I was referring to was the commit following the revision you tested (d4b5dd31).

Can't recreate anymore here :)

Closing as resolved for now, we can reopen if the issue still appears for someone.
