NoQ added a comment.
That's the one:
typedef __typeof(sizeof(int)) size_t;
void *malloc(size_t);
void escape(int **);
struct S {
int *ptr;
};
void foo() {
struct S s1;
s1.ptr = malloc(sizeof(int));
escape(&s1.ptr);
}
After the patch the allocated symbol no longer escapes. It didn't end up having
much to do with destructors. I'll also think about it a bit more.
