I have no idea how to go to solve this SIGSEV ????

what is the output of
catchsegv yade script.py
?
or simply how you run yade, just catchsegv in front of the command

Cheers
Jan

Dear Jan,

Thanks.
The upper part of the catchsegv output is the relevant part.
There some lines concerning Yade, but I cannot tell where is the problem..

Hi,

Can you specify (if not already done ?) your operating system ?

HI
I am using either Opensuse 15.4 or 15.5 with the same result

luc

another strange behavior when I am trying to go behind the output display error :

starting gdb with display crashes
then restarting with "-n" don't crash
the restarting with display works !!

see the extraction of the process (some thread are erased) :
