I'm not seeing any attached files with the bug report. Would you be kind as to attach them again? Thanks.

If you don't use the images for the nodes, do you get the same problem?

On a side issue, your graph has a very tree-like structure. Circo does not work well with trees, as it tends to produce very big layouts. It would probably be better to use neato, sfdp, or fdp.

1: OK. I realized, that I need to use another layout engine. I used and it worked. I reported this because graphviz should not end with "assertion error".

2: Sorry I forgot, that images could be involved. I uploaded them for you. They seems to be OK. So it is not issue of corrupted image.

3: I tried to produce graph without images as you suggested... but this time result was "dot: failure to create cairo surface: out of memory". Which is OK, but I do not now how to try it.

4: I changed output to pdf (again without images). No memory problem but circo produced a white page... I half of the edges and result was ok. I tried to how many edges I have to remove (from the end) to get a result... I have uploaded file, which produces for me only white pdf page. If I remove the last edge, result is ok.

1. Agreed, but it is better if fixing the bug does not hold up your work.
2. No, but the images do change the geometry. Thanks. With the images, we can now replicate the bug.
3 & 4. The problem is that, for your graph, circo produces a huge drawing. For bitmaps, we run out of area (sometimes, we are able to scale it down automatically but the memory requirements may still be too much). For pdf, what you see will depend on the viewer. acroread shows a white page; the preview program on the mac displays the graph. The main lessons are that circo is not
right for your graph and that it's useful to use -Gsize=10 or something unless you're sure the drawing will be small.
