Worked: (optional)

Short description of error
There's a debug assert when using the knife project "cut through" option. Would most likely be harmless in release builds it looks like.

Exact steps for others to reproduce the error

Open provided blend: knifeproj-bug.blend

Then:

Invoke Mesh -> Knife Project
Change redo setting to turn "Cut Through" on
Assert

MEM_freeN(visit_bitmap); // visit_bitmap is nullptr and triggers the debug assert in MEM_freeN
