dot file which yields exception

anonymous — Mon, 10 Jun 2013 01:30:32 GMT

exception message is:

Invalid start token for statement (token is "<eof> ")

the comment at boost-test.cpp:5 is incorrect- test_dot was not null-terminated. (std::string was constructed from it using begin and end iterators).

from some experimentation, it appears that deleting line 12 in test.dot (i.e. the line containing a comment) causes the exception to not be thrown from read_graphviz.

I fixed that issue. Your code still breaks because you do not define a "shape" property in your dynamic_properties object, but the file appears to parse correctly.

thank you!
