<p>ok, I believe I've now a fix in
<a class="moz-txt-link-freetext" href="https://github.com/OSGeo/gdal/pull/9700">https://github.com/OSGeo/gdal/pull/9700</a> . Probably a subtle
multi-threading issue related to different memory ordering between
M1 and Intel CPUs (or just that it was easier to trigger on M1)<br>

<p>Hi,</p>
<p>I've investigated that today, and I can quite reliably trigger
a similar error with our existing tests on CI, but this is
impossible to diagnose further without direct access to a
machine where the error triggers (when simulating taking the the
error code path on Linux, the fallback code works, whereas it
doesn't on OSX Arm64, so there's something quite subtle
happening here). So if someone has a OSX Arm64 and is willing to
give me ssh access to it, that would be welcome.</p>
<p>In the meantime, I've submitted <a

which is just a workaround to disable (by default) the threaded
RTree creation on that platform. It can be explicitly enabled by
setting OGR_GPKG_ALLOW_THREADED_RTREE to YES</p>
