--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
Thanks. That seems correct. If in the first visit a.scopes was allocated, but
an error occurs later or in the second visit a.scopes isn't freed. Except in
the case of a realloc failure. It would make sense to also not dealloc in that
failure case so we can always free on failure before we return the error as you
suggest.
BTW. Do you know what why result was negative (I assume it was negative, it
could in theory also be zero, but that would be surprising if that would cause
the leak)?
