-Subject: [PATCH] fix: out-of-bounds write on invalid label
-
-When the label for a node cannot be parsed (due to it being malformed), it falls
-back on the symbol name of the node itself. I.e. the default label the node
-would have had if it had no label attribute at all. However, this is applied by
-dynamically altering the node's label to "\N", a shortcut for the symbol name of
-the node. All of this is fine, however if the hand written label itself is
-shorter than the literal string "\N", not enough memory would have been
-allocated to write "\N" into the label text.
-
-Here we account for the possibility of error during label parsing, and assume
-that the label text may need to be overwritten with "\N" after the fact. Fixes
-issue #1700.
