Hello Joachim,
I got the idea that I should be able to produce a broken setup too ;-)
And yes, just by installing nvidia-driver into my test VM I get the crash below.
It is caused by trying to retrieve GL_NUM_EXTENSIONS.
This fails due to our broken setup and leaves the
variable that should store it uninitialized
and is then used for the alloction attempt.
I was not able to reproduce it that way in a
Buster/testing VM - abiword just opens after two libEGL warnings.
Therefore it looks like upstream have fixed this already.
Kind regards,
Bernhard
