Summary0000414: Dot "lp" buffer overflow on Windows, Linux and Mac
Description
The problem occurs when the input graph is large. The resulting
output file very commonly contains "lp" attributes with the
value "-2147471648,some_other_number" or "some_other_number,-2147471648".
This number is very close to +\-2^32/2 suggesting that it could have been
the result of a buffer overflow somewhere along the lines.



If we now view the graph in dotty or a postscript viewer, we notice that the
affected lp's are ignored. In Grappa, we aren't shown anything when viewing
graphs containing these lp's.
