Cannot change node shape

Help
1

(Sorry for the duplicate post, I thought I had fixed the issue but I was running dot on a different file!)

Input file:

digraph Blah {
  rankdir="LR"
  node [shape="box"];
  A -> B -> C;
  B -> D;
}

When I run the command dot -v -Txdot gt.dot > gt.xdot , it fails with “Illegal instruction”.

But when I remove the node [shape="box"] line, it works. How do I fix it?

Does it crash if you change the output format - to png or svg?

Yes, the same error.

I tried with Graphviz built with CMake on Windows and it worked fine. If you think this is a bug, you should open an issue at https://gitlab.com/graphviz/graphviz/-/issues/new. If you can’t or don’t want to, please provide the same info here as the issue template asks for.

Here’s my output:

After testing it out some more it seems to be an OS issue. I was using iSH (https://www.ish.app), which is an emulated Alpine Linux that runs on iOS. Since the same file works on ordinary Alpine Linux and Windows, it seems to be an issue there. I have filed an issue with iSH.
