Curves with curve modifiers are not translated to mesh correctly and can't be used as a target for constraints and modifiers predictably #63871

System Information
Operating system: W10
Graphics card: GTX 1080TI

Blender Version
Broken: 2.80-d966c2f0c2ad-win64
Worked: 2.79 master build

Short description of error
If you ctrl+a and press "visual geometry to mesh" on a curve that has a curve modifier, the resulting mesh you're getting is as if you didn't have that curve modifier at all. This was not the behaviour in 2.79b. Also, if you assign any constraints or assign this curve as a modifier for objects, you'll have it deformed as if the deforming curve doesn't have the curve modifier.

Exact steps for others to reproduce the error
Ctrl+a on the bezier curve in this sample file

There's also something strange going on with linked curves (that share the same data), check this thread out https://developer.blender.org/T61184

Guys, can this get fixed? It's been in for a very long while already.
