SUMMARY: UndefinedBehaviorSanitizer: nullptr-with-offset /test/10.5_dbg_san/strings/strcoll.inl:251:25

Setup:

Compiled with a recent version of Clang (I used Clang 18.1.3) with LLVM 18:

    # Note: llvm-17-linker-tools installs /usr/lib/llvm-17/lib/LLVMgold.so, which is needed for compilation, and LLVMgold.so is no longer included in LLVM 18

    sudo apt install clang llvm-18 llvm-18-linker-tools llvm-18-runtime llvm-18-tools llvm-18-dev libstdc++-14-dev llvm-dev llvm-17-linker-tools

    sudo ln -s /usr/lib/llvm-17/lib/LLVMgold.so /usr/lib/llvm-18/lib/LLVMgold.so

Compiled with: '-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++' and:

    -DWITH_ASAN=ON -DWITH_ASAN_SCOPE=ON -DWITH_UBSAN=ON -DWSREP_LIB_WITH_ASAN=ON

Set before execution:

    export UBSAN_OPTIONS=print_stacktrace=1:report_error_type=1   # And you may also want to supress UBSAN startup issues using 'suppressions=UBSAN.filter'. For an example of UBSAN.filter, which includes current startup issues see: https://github.com/mariadb-corporation/mariadb-qa/blob/master/UBSAN.filter

Bug confirmed present in:
MariaDB: 10.5.28 (dbg), 10.5.28 (opt), 10.6.21 (dbg), 10.6.21 (opt), 10.11.11 (dbg), 10.11.11 (opt), 11.4.5 (dbg), 11.4.5 (opt), 11.7.1 (dbg), 11.7.1 (opt), 11.8.0 (dbg), 11.8.0 (opt)
