RTOS/MSP430F5528: A C language "if" statement fails to execute correctly

What happens if you add an assign statement:

temperature = 3000; rather than setting it via the debugger?

What happens if you use:

if (3000 > hi_temp_threshold)

Did you type in your code above, or copy and paste? If you typed it, look closely for any extra semicolons.

Turn off optimization.

Create a small test case, test it, and post it here.

This works fine on my MSP432P401R:

 * MSP432 GPIO - Toggle Output High/Low
 *
 * Description: In this very simple example, the LED on P1.0 is configured as
 * an output using DriverLib's GPIO APIs. An infinite loop is then started
 * which will continuously toggle the GPIO and effectively blink the LED.
