DescriptionHaving any more then a few cut prims physical will cause a simulator crash. This is really noticable with the use of vehicles that use cut prims for tires to reduce surface friction.

Steps To ReproduceRez a cube.
Cut cube.
duplicate cube at least 4 times.
set all cubes physical.
Additional Informationran a git bisect and this is the output

This is happening every time on Windows 7. There is no crash on Linux. This means that no one is running anything on windows because this crash makes any linkset vehicle or region with cut objects crash the simulator.

I thought it was some problem with my configuration. Little did I know it was just my Operating system that is the problem :), I did not think it was serious until it started happening on another test grid after a upgrade.

I have several physical linkset vehicles running on a region which is hosted on a Win7(64) system and they don't seem to cause crashes. Could it be limited to Win7-32bit or to people not running Bullet in a separate thread?

I just checked in (db2a22e6224164dc80736340c791308150890d03) new BulletSim DLLs which fixes this problem on my test system. Please test and report.
