Comments:
Is there an upper size on the #nodes and/or #edges that dotty can handle? I've 3GB free disk space, could that be a problem? -- no ideas, beyond that...

[erg] The immediate cause is a non-ascii character in the input file. For some reason, something then goes wrong in lefty and it gives up. On unix, an error message is printed about the parsing problem; on windows, no message is seen. So, there are two problems: why does an illegal character cause a problem, and how can parse errors be reported on Windows?
