Worked: (optional)
Short description of error
Two intersecting volumes makes a very visable clear line.
Exact steps for others to reproduce the error
Make two cubes with a volume shader, don't make the too dense and maybe add a procedural texture.
take one halfway inside another

Not even completely sure if it's a bug at all, but it's a bit anoying.
I bet for now i have to combine the two shaders into one cube. But my way would be quicker if it worked.

Added subscriber: @MarcinTwarowski
In the example file you attached there's an obvious z-fight where faces of the cubes align.
When rendered cubes don't blend well:
However if I move one cube slightly in x and y axis, so that z-fight is gone:
volumes blend quite well:

Oh really, i didn't know volumes was affected by z-fighting.
Changed status from 'Open' to: 'Resolved'
It worked, thanks.
I really didn't though volumes was affected by this.
A bit annoying, but i guess it's more of a overall CAD problem than blender
This could still be considered a bug, I'm not sure.
