In REAL C the right way to handle that would be to declare the variable
volatile, eg:
volatile int mutex;
and that forces the compiler to always use the in-memory copy. I don't know if
that exists in IC, but if not I bet all variables are implicitly volatile
(otherwise memory writes to chip registers wouldn't work right).
