Technical details
The vulnerability is a use-after-free in the SkipEmptyRow macro when skip_empty_rows skips an empty line. The parser borrows the caller's scalar variable via bind_columns without taking a reference, but incorrectly calls sv_free() on it during row skipping, decrementing the caller's refcount and causing premature deallocation. Later code accessing the freed variable can crash or execute in freed memory. The fix guards the two sv_free() calls with is_bound checks, matching guards already present in error paths.
