Bullet crashing while doing the collision test

[vipinjs]

Hello,

I am trying to detect collision between an avatar and a geometry as shown in picture. I used btGImpactTriangleMeshShape as the collision shape for both the objects.
I compute the collision using contactTest(obj, callback) function. But the program crashes for the geometry shown but works for other geometries quite well.
Any input regarding this is highly appreciated.

regards,
Vipin
