Re: [orca-list] A page that can crash orca

[Joanmarie Diggs <jdiggs igalia com>]

This bug seems to be yet another case of broken Gecko hierarchies.
Asking for the index in parent for objects is sometimes returning -1
which indicates something is invalid. I worked around this condition and
stopped the Orca hang. That's the good news. The bad news is that if the
structural navigation object you are expecting to navigate to is a
sibling or a descendant of the object with the invalid index in parent,
the odds are extremely good that Orca will skip over it. There is
nothing I can do about that in Orca I'm afraid. We need valid indexes in
order to find siblings.

Thanks for the report!
