Usd file with an ArnoldUsd node that loads

[arnold-support]

Describe the bug An ArnoldUsd node that loads a usd file with other ArnoldUsd nodes crashes the host application. I crashed Maya, Houdini, and 3ds Max (using the latest release plugins for Arnold 6.2.1.1)

kicking a usd file didn't crash.

chrome-spheres.usda has three ArnoldUsd nodes. They each load chrome-sphere.usda. chrome-spheres.usda.txt chrome-sphere.usda.txt

Scene file that you can kick (it didn't crash for me). nested-ArnoldUsd-nodes.usda.txt

To Reproduce

1. In Maya, create an aiStandin and load the attached chrome-spheres.usda file. Maya crashes and sends a CER report (I submitted 310222060, 310221421, 310222102, and 310220645).
