[Closed] meshOp.breakVerts problems

I want to break some object’s vertices (usualy not all), but after that I need to know which verts was unified. So, breaking of vertice creating new vertices that I collecting into one group (array).

I wrote this script (you can copy and easy test it): 

function breakVertices object = 
    (
    	progressStart "Breaking into break groups..." -- show progress bar
    	local t = timeStamp()
    
    	local mesh = snapshotAsMesh object
    	local breakGroups = #()
    
    	local vCount, init_vCount = mesh.numverts
    	for i=1 to init_vCount do
    	(
    		vCount = mesh.numverts -- store vertices count before break
    		meshOp.breakVerts mesh #{i} -- break the vertice
    
    		-- disable data collecting start here
    		breakGroups[i] = #()
    		breakGroups[i][mesh.numverts-vCount+1] = i -- add base vertice as last one (it will init known size array)
    
    		for j=1 to (mesh.numverts-vCount) do -- collect new created vertices
    			breakGroups[i][j] = (vCount+j) --*/
    
    		progressUpdate (i*100.0/init_vCount) -- update progress bar
    		if( getProgressCancel() ) then exit -- progress bar cancel button pressed
    		
    		--gc() -- free memory
    	)
    	
    	print( "Breaking total time: " + ( (((timeStamp()-t)/1000.0)) as string ) )
    	progressEnd() 
    
    	return breakGroups
    )
    
    -- testing interface
    rollout VertNormals_roll "VertNormals" 
    (
    	button getBtn "Break into break groups"
    
    	on getBtn pressed do
    	(
    		undo off
    		(
    			disableSceneRedraw()
    
    			if(selection.count > 0) then
    			(
    				gc()
    				print( "Break groups: " + (breakVertices selection[1]) as string ) -- use the function
    			)
    			else
    				messageBox "No object selected!"
    
    			enableSceneRedraw()
    		)
    	)
    )
    
    -- create the rollout window and add the rollout
    if VertNormalsFloater != undefined do closerolloutfloater VertNormalsFloater
    	
    VertNormalsFloater = newRolloutFloater "BreakVertices Floater" 200 100
    addRollout VertNormals_roll VertNormalsFloater
    			

Works fine, but [b]meshOp.breakVerts[/b] throws "Unknown system exeption". It happens with more complicated objects, with mapping, materials etc, less with standard primitives.

Second problem is fact the breakVerts function seams to making hudge memory leaks. You can check it in windows process manager (disable data collecting code to see it is't the problem).

Maybe there is better way to break vertices?
