Curly Brace deletion behaving unexpectedly

[Swaggermuffin64]

struct Node *reverse_list(struct Node *head) {
    struct Node *prev = NULL;
    struct Node *current = head;
    struct Node *next = NULL;

    while (current != NULL) {
        next = current->next;
        current->next = prev;
        prev = current;
        current = next;
    }
    return prev;
}

If your cursor is on the first character of this function, and you run da}, it will delete the inner curly brace while loop. In regular vim, it would delete the outer. Note da { would work correctly.
