So, it's: - not related to bitmap code, - not only s390 issue, and - fires with CLANG when GCOV and KASAN are enabled together. Is that correct? If so, I can disable the test for CLANG+GCOV+KASAN configuration unless the above is fixed. Nick, can you please confirm? Because it's a build breaker, I'd like to have it fixed in v6.5. Thanks, Yury
