ExampleBrowser raycast issues and crash.

[dor666]

Hi,
I can only reproduce it using Bullet 2.85 release binary .
If I compile master or sources attached to the same release using VS2013 its working fine.

Symptoms:
Run bullet-2.84_vr_win32_executable\bin\App_BulletExampleBrowser_vs2010.exe Double click on Benchmark->Raycast. Rays are poping and hiding in random directions. After 5-60 sec app crashes, if not select "3000 boxes" and "raycast" again.
Crash is caused by reading invalid pointer inside glBufferSubData. Memory shows a lot of 0xfeefee passed to glBufferSubData.

Issue is both on Intel and Nvidia cards.

This might be related to VS2010 used to compile executables. I have only VS2013 to test it right now.
Compiled with VS2013 rays are draw nicely and no crash occurs. Enabling runtime checks (/GS /RTCs /RTCc /RTCu) did not reveal anything wrong.

Crash place: App_BulletExampleBrowser_vs2010.exe!00b19427()

Params passed to glBufferSubData():

• offset: 0
• size: 32000
