Short description of error
We're using creases a lot in the company for modelling. Since a few days, the master branch fails to compute them correctly in the SubSurf modifier, when there are certain modifiers before that present in the stack. See the commit details I provided above to identify the commit that caused this.

Have a look at the example file here

where a cube has one edge creased and a few modifiers on it. When you open the file, the result looks like expected, the SubSurf computes the creased edge correctly. However, if you enable either the bevel or the mirror modifier before the SubSurf in the stack, the crease disappears. This does not happen with the current stable release 3.3.

Weird detail about it: as long as you are in Edit Mode, the final result displays just fine.

Exact steps for others to reproduce the error
Open the provided file

and enable one of the modifiers as per screenshots:

when you open the file:

when you enable the mirror modifier:

when you then toggle into Edit Mode:

Never mind, it got resolved last night!
