Bug Description

OS: Windows 7 64bit
Build: Custom 1.10.1206d with Python 3 (Bug also occurs in Python 2 build)

The attached .egg file crashes Panda when loaded as an actor, as it is in the attached main.py when 'Q' is pressed. The .egg file was created using the latest version of YABEE from GitHub. The same mesh exported without the armature loads correctly.

Thank you for reporting! This turned out to be a low-level regression in 1.9.0: MSVC 2010's stable_sort implementation seems to (under unknown conditions) perform a self-move-assignment (ie. "a = std::move(a)") which is of questionable legality in C++ so some of Panda's internal classes weren't designed to deal with that situation.

I checked in a fix. I've made a new build available for your configuration here:

Thanks again!
