GDB backtrace with latest master 1b1b3f044c
SUMMARY
Face detection crashes due to pure virtual method call in LoadingCache.
STEPS TO REPRODUCE
1. Build digikam from master commit 1b1b3f044c (snapshot of "7.2.0 beta").
2. Open digikam with a large collection of images (over 27000 JPEGs).
3. In the face detection settings, choose the "Work on all processor cores"
option.
4. For workflow, use "Detect faces" and "Scan again and merge results".
5. Start the face detection by clicking the "Scan collection for faces" button.
OBSERVED RESULT
Digikam crashes.
EXPECTED RESULT
Digikam should not crash. It should detect faces in my collection.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux 5.8.11-1-MANJARO

It was closed as resolved at the same time as this bug:
https://bugs.kde.org/show_bug.cgi?id=426175
See the GDB backtrace attached. I attempted to run without GDB at first, but
crashed after around 20 minutes with around 30 % completion. When I ran again
with GDB, digikam crashed around 79 % completion.
