I've attached a patch that should address this (and other) problems.
While the crash you noted was squarely the fault of OpenVRML, fixing it
led to a crash due to some invalid data in room.wrl. The node
WALL02-FACES uses 24 as a coordIndex; but there are only 24 coordinates.
(Coordinates are indexed starting at 0; so 24 is out of range.)
Nonetheless, crashing is not an appropriate response to invalid input;
so this, too, has been fixed. This patch makes OpenVRML skip invalid
coordinate indices (along with any subsequent indices in the same
polygon).
This patch was created against the trunk; but I suspect it will apply
cleanly to 0.17.6.
