Hi Jon,


thank you for the quick response!

It turned out that the segfault was not due to the compiler, but that it
appears if I start prj without a running x-server. On the older machine,
I had it in the background. On the Catalina machine, after starting x, I
was able to run prj, too. I am wondering if one should test for an
xserver before calling xlib functions, which would probably avoid the
error message I got.

Interestingly, I got this error before I entered a file-name.

That is what I am doing for now. If anyone could replicate this, it
might lead to a problem in the processing of geometry though.


Besides that, I found another problem when editing constructions with
cavities. On 13.3.11, prj crashes if I add a "gap" to a construction
right after confirmation to do so. I am able to add the construction to
my construction database using an older version of ESP-r, and then use
the that db with 13.3.11, so this hints at a problem introduced in a
recent update.


Best, Lars.
