Can't confirm that here, maybe it's related to your crash in #43903. Could you do the [dll ]] test again? Would also be interesting to see your [ http:*blender.stackexchange.com/a/9121 | system-info.txt .
It is not related to my old bug because it is now crashed on another computer, sorry I didnt add my configuration. It is Core i7, Geforce 770. I also see, that I wrote 2.47, I mean 2.74 of course :) Previous bug what you mentioned is ok on current configuration. Are you sure that you are testing exr file from File Output? not PNG from normal Output. Here is my output file:
www.cenda.cz/temp/exr.0097.exr
, which is crash after load to Node editor (to composition as Image node). I tried it load to Node editor to Material and it is working well, so problem is only in Composition Node Editor. It is also crashing with your dll.

Okay can confirm that now .
@LukasTonne, getting a failed assert in ImageNode::convertToOperations(...):
Adding a non-Null check solves the crash but I still get errors printed to the console and the image that shows up doesn't really look like I would expect it. Looks like something goes wrong during saving from the compositor?

@JulianEisel, Lukas is the wrong guy for the compo issues. If the issue still exists please re-assign to me.
Yep, it still exists.

This has been around for SEVERAL versions.

I can't really reproduce crash in current releases, but can see the crash with current master. And there i need some inputs from @dfelinto.
Dalai, the issue is that it's a multilayer file and for some reason it does not have any views. I'm not sure if it's issue with saving the file (missing view on save) or some missing NULL pointer check on read. But i would only say here that files without views should not crash blender.
In Mac I did get a crash with 2.74

(aka, the commit before multiview):My suspicious is that the compositor assumes to have a 'Combined' pass and the image doesnt have it (it has an Image pass instead).
Now to master: It's fine for the file to not have views, but RenderResult should always have a view. The initial crash is indeed multiview related, but it's simply masking the real problem which is likely the same as above. I can help looking at it later.
That said I should be able to help with this since I
@dfelinto, I'm happy to look into compo-related issue, but for that i need multiview-related fixed first. Think it is possible to reproduce multiview-related one without touching compositor?
@Sergey in master if you hide the properties panel of the Node editor and add the Image Node with the broken EXR you get the following crash:
Which seems to me exactly as the original error, and not related to multiview. What I propose is, you look at this compo issue, and once this is fixed I enable the property panel and fix the multiview part. There is a (high) chance that the multiview issue is gone once the main one is solved.
I can help you looking at it later, but I would rather tackle the other pending multiview problems first.
@Sergey btw, you can enable exr_printf() in openexr_api.cpp::1615 to get tons of useful debug printing.
