LPC Xpresso 824 having problems working in Release mode

I am having trouble converting a program into release mode for further development and testing.  I have reached the memory limit of 32k in debug mode and release will compile with only 26k leaving more room for functions.  However when I compile in release mode, then program on my board nothing happens.  Upon resetting it should blink a LED 5 times then begin printing debug on UART0.  However nothing happens and I get no debug prints.  It works in debug mode but not release mode.  I have already made sure that all the other project that I use code from/reference are in release mode as well.  Is it possible that the pin mapping changes between debug and release?

 

I am using a generated hex file to program the board.
