Variable is not getting assigned to 0.

[venkateshgv]

We are working on MC9S08QD4 with Code Warrior v6.3. When we assign 0 to a variable it is not getting assigned to 0 and it works with the previous value sometimes. Please share your feedback.

Could you share a reproducible example?

for example, if you have something like:

int i;

i = 10;

i = 0;

i = 20;

then the compiler will be able to optimize this.

Hi,

I wonder the problem is because of the optimization.

I suggest you cast the variable as "volatile" then try again. for example.

volatile int myval;

Have a great day,
