Re: (ITS#9037) observing crash in mdb_cursor_put()

[vporof@mozilla.com]

Hey folks.

=46rom Myk=E2=80=99s investigations in the previous followup, it seems =
that the suggested changes to `mdb_cursor_init` to avoid using an =
invalid DBI might not be solving the actual issue, given the behaviour =
of `mdb_page_search`.

It=E2=80=99s also causing the seemingly correct test program to assert =
when it wasn=E2=80=99t before. It=E2=80=99s unclear whether this should =
be the case or not, perhaps Howard can confirm the expected behaviour.

In any case, we=E2=80=99re wondering if there=E2=80=99s been any other =
progress, or if someone managed to reproduce this issue? Shipping new =
features built on top of LMDB in Firefox is currently blocked due to =
these failures, so any additional info would be helpful.
