Is this a mex routine that you wrote? Do you have the source code? The error message is pretty clear ... memory access violation, so the code has a bug.

If it worked fine on 32-bit, then of course the most likely problem is you missed something in the integer or pointer size conversion in your code. The dump file might point you to the routine, but regardless I would suggest you go through your code line by line to try and find what you missed. If the code is not too long you could post it and we could take a look as well. Also, be sure to compile with the '-v' verbose option to see what the compiler thinks of your code ... maybe there are some warnings that will tell you exactly what the problem is.
