Am I right, that writeSTL is not implemented, as I get only empty STL file with text header and tests are missing for this method? Or is just something broken at my side?

I think that you mean writeSTL, writeSTEP works for me but not writeSTL

Below code results with segmentation fault:

var occ = require('occ').occ
var box = occ.makeBox([0,0,0],[100,100,50])
var cyl = occ.makeCylinder([50,50,-10],[50,50,60],40)
box = occ.cut(box,cyl)
occ.writeSTL("somefile.stl",box)
