Said otherwise, there is some degree of probability accepted by industry and regulations about that some thing at a building made according to the standing rules may not entirely work without any glitch. Some different detail of more cost might have not shown the problem at hand, but could then be neither in accord with the intent, will to pay, or aesthetic standards of the user.

The floor slab and the wall are expanding and contracting at different rates, thus the differential movement. As ishvaaag noted, there should be a defined joint at this location.
RE: plasters affected by rain and DPC
ok what Ron says make also sense that the surfacebed and the wall behaves differently so do you provide there everytime a plaster joint?
it seams for me that the weet ground is weeting the wall and the watter goes up to the PCD and comes out there.
It seams I should rather provide a drainage or a slooping apron or something like this

When the wall absorbs water, but the slab does not, you have the opposite condition with the same result.
If water is bleeding from the crack, it is likely coming from an accumulation of moisture in the hollow cells of the masonry and weeping out at the crack. If this is the case, you will likely see some "efflorescence" or calcium-laden deposits at the crack.

but only that I never noticed a joint in the plaster between the surfacebed and the walls. This is strange
I think to fix this problem now I will try to convince the client to provide an apron around the wall or a drainage pipe and gravel above to collect the water and take away from the building.
