    Description

      1. Checked out qt5.git, initialized submodules qtbase: 
        qtrob@rob-desktop:~/dev/src/qt-dev_02.21-base_svg$ git submodule status |grep v6
b82061688d8a556d1d7d7f89e48642fc629a7a90 qtbase (v6.0.0-beta5-6133-gb82061688d)
      2. Configured Qt with UBSAN: 
        qtrob@rob-desktop:~/dev/clang-10.0.0/qt-dev_02.21-base_svg-fubsan$ cat config.opt 
-platform
linux-clang
-opensource
-confirm-license
-no-widgets
-prefix
/home/qtrob/dev/clang-10.0.0/qt-dev_02.21-base_svg-fubsan/qtbase
-release
-static
-no-gc-binaries
-sanitize
fuzzer-no-link
-sanitize
undefined
      3. Built this: 
        cmake --build . --parallel

        I ran into a build error.

      4. Logging the error and attaching it: 
        qtrob@rob-desktop:~/dev/clang-10.0.0/qt-dev_02.21-base_svg-fubsan$ VERBOSE=1 cmake --build . > build.log
