Cortex A9 (IMX6) : Enabling branch prediction aborts

Hello,

I am using imx6 (cortex- A9) board, and my mmu environment is as follows
            mmu   - enabled
            L1 data cache - enabled
            L1 instruction cache - enabled
            D-side prefetch - enabled
            L2 cache - disabled
            Branch prediction - disabled

With this environment, my code runs for a longer time (more than 12 hours) with out any issues.
But, if I enable branch prediction, the code aborts in few seconds, at random addresses.
I am not able to understand what goes wrong.
Are there any special option which I have to consider while building my code.
I am using GCC as the compiler.

Note : In my code, I am using a static library, which was given by our vendor.

Any help would be great.

Thanks,

Gopu
