I apologize for not noticing this bug earlier. It's indeed a bug, but
I don't think your suggested fix is right. At that point in the code,
nothing has been done to give errno a meaningful value, so ->err_no
should just be cleared to 0.
I will apply this patch later today, along with some other changes, if
bootstrap succeeds.
