I can't speak for the sanitizer bot, but for llvm-clang-x865_64-gcc-ubuntu you should be able to reproduce some of the failures by running:
- cmake ../llvm-project/llvm -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=Release -DCLANG_ENABLE_CLANGD=OFF -DLLVM_BUILD_RUNTIME=ON -DLLVM_BUILD_TESTS=ON -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_INCLUDE_EXAMPLES=OFF '-DLLVM_LIT_ARGS=--verbose -j48' -DLLVM_USE_LINKER=gold '-DLLVM_ENABLE_PROJECTS=compiler-rt;clang;lld;cross-project-tests;llvm;clang-tools-extra' -GNinja
- ninja check-fuzzer
