Backporting r12-1005 (see pr100551) fixes the segfault in comment#0 also
for 10-branch.

Fixed on 10-branch with r10-10384.
Cherrypicking that patch however does not fix the issue on 9-branch.
There must be something else missing which would need backporting.

After the backport this should have been marked as 9-regression. Doing so now.
