Follow-up Comment #57, bug #53733 (project octave):

I don't know. But removing the call to imwrite makes a larger sized argument

javaaddpath (".")
graph = javaObject ("Baz");
graph.addNodes (1:100000000);

work just fine. It takes a while and is busy most of the time, doing
Octave-to-Java array type conversion I suspect, but exits without error.

Simply calling 'imformats' to print the image format types supported by
GraphicsMagick, instead of imwrite, is enough to allow the 1:1e6 argument to
lead to a segfault.
