Is the abeIslandIterator's next operation shared for the multiple iterator?

Hi all.

I'm using Virtuoso IC6.1.8-500.19 and I want to do some boolean layer operation by ABE (Advanced Boolean Engine).

When I'm using the abeIslandIterator simultaneuosly for the several abeLayer, the next operation of iterator does not working that I expected.

The code reproducing the unexpected result is as below.

abeInit(cellView)

abe_A = abeLayerFromCellView("A")

abe_B = abeLayerFromCellView("B")

abe_A_island_iterator = abeIslandIterator(abe_A)

abe_B_island_iterator = abeIslandIterator(abe_B)

while(island = abe_A_island_iterator->next

    println(island)

)

abeDone()

I expected that the point arrays for the layer A are printed, but those for the layer B are printed.

Do I misunderstand the islandIterator?

This is a fairly nasty bug - I see no reason why the iterators should interfere with each other as they are supposed to be separate objects. I've filed a change request (CCR) 2796759 but it would be better if you contact customer support yourself and ask for a duplicate yourself (it's hard for me to set an appropriate severity because I don't know how easy it would be for you to workaround this bug). Please reference the existing CCR number when you report this.
