Description

```
What steps will reproduce the problem?
1. Calling importer.ImportFile(path.dae), importer is AssimpContext class
2. I think that it needs to be larger model (> 10 MB)
3. I've tried to reexport model in Maya/3ds Max, still crashes

What version of the product are you using? On what operating system?
I'm using newest version (3.1.1) on Windows 8.1

Please provide any additional information below.
Smaller ones are working just fine (up to 4 MB)
It just crashes without any exception.
There is dl link to one of the model which crashes

Research direction

Start at the AssimpContext importer.ImportFile(path.dae) entry point and reproduce the crash with the linked larger Collada model on Windows 8.1. Compare it with the reported working files up to 4 MB and the failing files over 10 MB; done means the model loads without an unhandled crash or the failure is clearly diagnosed.
