--- Comment #1 from Andrew Morris <morrand276 at gmail.com> ---
I can confirm the same problem is occurring on FreeBSD 12.3 on Marble 22.08.1
(FreeBSD port version 22.08.1_1), with Qt version 5.15.5p165, Plasma 5.24.6_1.

It's actually showing up in two different ways for me. If the GeoDataFolder is
created in a different function, then within begin(), *this is null, and the
attempt to set the d pointer segfaults, apparently because it's trying to
access memory at this+0x18 or something like that. If it's created within the
same function, then *this is some absurd value like 0x7fffffffe598 and the
attempt to set d fails with a bus error. These seem to just be different
expressions of the same problem.

I too can access at(), first(), and other methods within GeoDataFolder without
any trouble, and they seem to return sensible results. This problem seems to
affect just the methods that return a QVector<GeoDataFeature*>::Iterator, which
are begin() and end().
