0006148: Channeled stone falls into constructed wall below
Channeling untouched stone one z-level above a constructed wall always results in the mined-out stone being transported into the tile with the constructed wall.
Loo'k'ing at said wall gives a report similar to this:
gabbro
Schist Block Wall
No tags attached.

It sounds like this is a side effect of what was meant to fix the root problem described in 0005877 (i.e. channeling out a tile containing an item causes the item to fall down, roll across the ramp, and collide with a dwarf down below) - it's moving the item down by 1 Z-level so that doesn't happen, but it's neglecting to handle the case where channeling through the floor does not remove the wall on the Z-level beneath it (namely, when there's a construction there) which causes the item to be left embedded inside the wall.
