You're replying to a member of the release team. I'm well aware of the
openscenegraph transition... :-)

Indeed. And those changes look like they broke simgear's ABI.

We know for certain that openscenegraph broke ABI - that's why it
changed SONAME and is the whole point of the transition. simgear, otoh,
appears to have silently broken its ABI, hence the crashes observed in
fgrun. It that is the case, then simgear should also change its SONAME
and its reverse dependencies (including fgrun) should be rebuilt to use
the new SONAME.
