Nah, it's not really a bugfix here.

Patches sent to stable should fix actual bugs or failures.

Sure, it's a defect, but it's only a logical one, not an
actual one. It doesn't/can't fail in practice.

This is only a single symbol and so it can't overflow the
initial allocation.

Besides that, the return value of the containing function
is ignored.
