Here is a demo file untitled_crash.blend. Just over the mouse in the viewport.

P.S. File is saved from gdb, and still has operator running. This might be another problem.

@ideasman42, you have better idea of cases when assert is really needed.

In this file scene->toolsettings->unified_paint_settings.last_location is {-nan, 4.592e-41 # DEN, -nan}.
This cause ED_view3d_project_float_global to fail resulting in the assert.

If I'm not mistaken, the value of last_location is obtained when reading the file.
