dng_sdk started failing with AFL the 15th December and it looks to be an issue in the compiler:

was llvm updated to the newest version? or is it still tagged to some weeks ago?
we had several larger changes for llvm 14 and I am not surprised if not everything is working.

The projects and the issue I listed here was fixed - the builds all switched green today.

There might be some other AFL build issues, Qt in particular https://oss-fuzz-build-logs.storage.googleapis.com/log-dba215ac-0acd-4e2e-830b-f868b5d9de1c.txt which fails with a different log.

Hi, Qt still/again failed today with a different stacktrace. Should I create a new issue about it? Or did the build still use an older image which didn't contain the fix?

Oh, I see the fix was not merged yet. So I'll wait and hope for that...

You probably already noticed that afl is also being extremely slow. Even successful builds of Qt in oss-fuzz literally take hours to finish. Should I create a separate report for that or is there anything else I can do to help?

well I need the fix merged first and then see if anything still pops up ... so if this still happens after #7026 then ping me.

Now that the fix is in, building Qt for afl just takes about 10 percent longer than for libfuzzer. This is not a significant difference to me. Thank you for the fixes!
