Summary0007179: Regionposition of Avatar who sits on a childprim in a linkset is wrong
DescriptionWhen a Avatar sits on a childprim of an Linkset, then his Regionposition is wrong by get it via the Linksetscript, or by llSensor from an autonomous script outside as well.

This has maybe to do with Mantis 0007043 ( [^])

This problem only appear on BulletSim. It works now for ODE since 7043 is fixed.

I am seeing this error.. possibly when an NPC that is meant to be sat on a vehicle is being created and sat down. I see the NPC in T-pose rather than sat down indicating it failed to find its sit target as programmed.

This is giving me nasty region startup issues... using BulletSim physics with latest Git master e.g. r/25568 27-Apr-2014

I am reporting it here in mantis 7191 as requested.

This error doesn't have anything to do with avatar region position errors, it is likely a separate memory corruption issue due to an issue somewhere within BulletSim.
