R2(size of move) value doesnt make sense. You may want to check how that value ended up there.
Have you checked FSR to make sure that you have Misalignment error?

Can u please tell me how FSR will help in debugging. Thanks

FSR bits 0-3 should tell you type of error generated. Alignment/Permission etc.
How did you find that you have Misalignment error?

When i decoded the call stack in the error record, i see a function call "Misalignment execption handler".. I am using C++ vectors...for which while removing the vector, the PROC_FAULT is triggered due to mis-alignment.
