I see that there are problems to solve with this patch. If a global variable is used at `realloc` or the pointer is a function parameter, it may have aliases that are not checkable. In the function code it is possible to detect aliasing. If all these cases are eliminated probably not much is left that is detected by the check, but we can test it.
