Summary0000631: dot crashing on very simple graph with only unconnected nodes and wide shapes
Description



running dot (no command line flags used) on given input results in sigsegv/application error(on windows)
width=1000 results in allocating a huge amount of memory on linux amd64/application error(on windows)



two similar outputs that dont crash:
(smaller width)
digraph g {node [width=909.9652777777777714];a;b;}



(added an edge)
digraph g {node [width=909.9652777777777715];a;b->c;}
Steps To Reproduce

digraph g {node [width=909.9652777777777715];a;b;}
Additional Information

[erg] The minlen parameter used in network simplex is an unsigned
short. The side-by-side large nodes create a value larger than will
fit. The problem is fixed here, but clearly there are lots of other
values which rely on the user providing sane values.
