How to prevent stack overflow in recursive function in C
The larger the RED Zone, the more likely we can detect a stack overflow when a function call allocates large arrays on the stack. However, in this case, the RED Zone takes away storage space from the stack because, by definition, a write to the RED Zone will generate an exception, and thus cannot be performed by the task. If the size of a stack is 512 bytes (i.e., 128 stack entries for a 32... unsigned var_t c,d; Multiplication overflow: There are two ways to detect an overflow: 1. if a*b>max, then a>max/b (max is R-1 if unsigned and R/2-1 if signed). 2. Let there be a data type of size n and range R called var_t and a data type of size 2n called var2_t. Let there be 2 variables of var_t called a and b. Range of var2_t will be R*R, which will always be more than the product of a

Better Embedded System SW Don’t Overflow the Stack

Detecting and avoiding stack overflow in embedded systems. One of the toughest (and unfortunately common) problems in embedded systems is stack overflow and the collateral corruption or crash that it can cause. Often, the consequences of a stack overflow manifest themselves far removed from the cause of the overflow itself, making the cause that much more difficult to identify and fix...
