Hi,

I have a DTL lattice I tried to run using the CLI (noX11) on Linux, but I get a segfault. I manage to make a minimal example attached.

It looks like if I use QUAD instead of DTL_CEL then it does not fail. It also seem to only fail when partran is turned on. Finally it works fine if I run in GUI, and it works with older CLI versions (not sure when this issue started).

The output I get is:

I can add that e.g. version 2.20.0.0 seems to work fine, maybe that helps narrow down what changed.

Dear yngve,

It's fixed.

Dear Didier,

As always, thanks for the prompt response. I checked the 2.21.0.0, but I still get segmentation violation?

Fast maybe but not very efficient and rigorous

In fact, there were two errors that accumulated and when I corrected the first one, I didn't even test the specific case that you had given me.
So it should be good now, I hope and I didn't change the version.

Didier

Thanks Didier, now it works again!
