I assume that differences in second example are caused by limited resolution of generated texture. Pixel values are averaged when stops are very close. Smoothstep version doesn't have this precision issues.
- Try latest release, 2.82.
The shader probably reached the limit on the number of textures. When this happens the terminal warns that the texture limit in the material has been reached.
Yes, you create a .blend file and reference images, see here:
Can you add tests for these new shader nodes?
This is a driver-specific problem. The shader probably reached the limit on the number of textures.
When this happens the terminal warns that the texture limit in the material has been reached.

Have confirmed was issue with the test image file - hadn't realised that the oiiotool had generated the image with incorrectly labelled channels. Thanks.
Yup.. Unless it changed in 2.82, T72339 [Momentary interface freezes while EEVEE rendering causes progress bar malfunction]:
EEVEE renders in the main thread of blender due to OpenGL limitations. Almost all calls to OpenGL needs to be passed to the driver via the main thread. This halts any other work that is handled by the main thread (python scripts ui updates). Same reason that running python scripts halts UI updates.
The progress status is send to the OS, so here it is updated correctly as the rendering is done by OS threads, not by Blender.
I used to think it is expected..

Pile of Garbage.
Windows and Linux with Intel graphics works perfectly.
Linux have constantly evolving opensource Intel driver.

This channel layout is nonsensical, how to interpret it is probably not defined anywhere.
File rgba.exr opened in gimp has no alpha channel, in krita it does.
Not working in 2.79 as well
Natron doesnt recognize the Y.Y channel as Alpha by default either...
For this EXR rgba.exr blender as a whole doesnt seem to be able to read alpha. (not sure yet whether this is correct or not)

@Zoltán András Heiner (Andari) Can you make a screenshot of the new file (so we have something to compare against)?
It looks fine for me on Ubuntu.
@Bryon Leung (GalerkinBunny) please submit a simplified test file.
