Wrong with alloc_size

[dingiso]

I’ve used llvm-cbe, but encountered many errors related to alloc_size. I discovered that the issue can be resolved by adding 1 to the argument of alloc_size. For example:

chown-8.2.cbe.c:1635:83: error: 'alloc_size' attribute argument may only refer to a function parameter of integer type
 1635 | void* realloc(void* _9237, uint64_t _9238) __ATTRIBUTELIST__((nothrow, alloc_size(1)));
