Tristan,
I've put in a change into our CVS so that, in the case of graphs larger
than the maximum bitmaps,
it will warn and scale the rendering down to fit, instead of (trying to)
error out.
Your graph now produces:
$ dot -Tpng kprof-output-graph.dot >out.png
dot: graph is too large for bitmap. Scaling by 0.46544 to fit
I can provide patches if you need them?
