android crashes after Recreating the Vehicle

[redmouth]

Urho3D library build commit ID: ea15976
Tested with x86 and armeabi-v7a version of static library libUrho3D.a

On Android platform, crash happens with the following steps:

• creating a Vehicle defined in sample 46 RaycastVehicleDemo.
• Removing the Vehicle Node and all it's child Wheel nodes
• Recreating the Vehicle, got the following crash:

Attached source files and stack trace. It works well on Linux.

stack trace:

Could you please update to current master and re-check if this is still reproducible?

[redmouth]

Great job, the latest master branch works on android. Thanks 👍
