 * mu_assert is a macro that returns a string if the condition expression passed to it is false.
 * When using it in a sequence of assertions, a function returns a message
 * as soon as encoutering a false condition (normally it means error).
 *
 * The space of this message cannot be allocated on the stack. 
 * It needs to be allocated with malloc or uses a global variable.
