Sfdp crash, regression in 15.1.1

1

Given the graph test.gv with content:

digraph {
  n0 -> n1;  n0 -> n2;  n0 -> n3;  n0 -> n4;
  n0 -> n5;  n0 -> n6;  n0 -> n7;  n0 -> n8;
  n0 -> n9;  n0 -> n10; n0 -> n11; n0 -> n12;
  n13 -> n14; n13 -> n7;
  n15 -> n16; n15 -> n17; n15 -> n18;
  n19 -> n20; n19 -> n21; n19 -> n18;
  n19 -> n2;  n19 -> n22; n19 -> n23;
}

then

❯ sfdp -Tsvg test.gv
free(): invalid size
[1]    1131228 abort (core dumped)  sfdp -Tsvg test.gv

Works fine in 15.1.0.

Sorry for reporting this here but creating a gitlab account is too much friction after they started requiring CC details for account creation.
