SUMMARY: UndefinedBehaviorSanitizer: invalid-bool-load /test/13.0_opt_san/storage/connect/ha_connect.cc:1719:23

Setup:

Compiled with a recent version of Clang and LLVM. Ubuntu instructions for Clang/LLVM 18:

  # Note: It is strongly recommended to uninstall all old Clang & LLVM packages (ref  dpkg --list | grep -iE 'clang|llvm'  and use  apt purge  and  dpkg --purge  to remove the packages), before installing Clang/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 lld-18

Compiled with: "-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_C{,XX}_FLAGS='-O1 -march=native -mtune=native'" 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' in UBSAN_OPTIONS. For an example of UBSAN.filter, which includes current startup issues see: https://github.com/mariadb-corporation/mariadb-qa/blob/master/UBSAN.filter
