Access violations in base MATLAB code

I am debugging a mex function using Microsoft Visual Studio 2010 Professional with MATLAB R2012b on 64 bit Windows 7 Ultimate. When I configure Visual Studio to break on Win32 access violations, I get dozens of breaks in MATLAB base code. This happens before I even load or call my mex function. The only way I have found to debug my program is to only configure VS to break on access violations after I have loaded and called my mex function and stopped in my code. This is very cumbersome.
Is there some way to make MATLAB avoid these violations so I can leave Visual Studio configured to break on them all the time?
FYI Here's an example of the kind of message I see:
First-chance exception at 0x0de62a68 in MATLAB.exe; 0xC0000005; Access violation reading location 0x00000004.
Thank you.

These exceptions are most probably coming from the JIT in the JRE so what you could try is running MATLAB without Java. To do so start MATLAB with the -nojvm option.

No I am afraid that this is not possible, the MATLAB GUI is Java based so disabling Java will turn off the development environment.
So you would either:
1. Somehow need to deal with the exceptions on the Visual Studio Side (perhaps someone else has further suggestions on that).
2. Have to temporarily live with not having the full MATLAB GUI when debugging these kind of specific issues.

In Visual Studio, Go To Debug > Windows > Exception Settings. Under Win32 Exceptions, Disable Access Violation
