Summary0000022: dotty fails on labels longer than 1018 chars
Description



I've built a GUI for my application using dotty. Nodes are of
record shape, and node labels can be long. It seems that lefty
uses a fixed buffer for parsing graphs.



A label longer than 1018 characters causes a segmentation fault
on my system. Quotes don't seem to count, but escape sequences
such as \n are counted as two characters, not one.
Steps To Reproduce

graph g{
aaaa
//make the previous line e.g. 1024 x 'a'
}
Additional Information

The "dot" command properly displayed a node having shape=record and
a label 3842 characters long.
