Hi,

I got this problem resolved by compiling llvm 7.0.1 on CentOS 8.3. It's 
a pretty big task as the disk space that
it took was 30 gigs for the compilation and 22 gigs for the target 
install part. I chose the 7.0.1 version because
that's what I had on CentOS 7.

Now I don't get that "Assertion 'get() != pointer()' failed" error but 
the Kivy application opens and works correctly in the X2go session.

Best regards,
