An uninitialized variable that caused a crash (https://lab.llvm.org/buildbot/#/builders/164/builds/11004) was identified using the memory analyzer, leading to the reversion of https://github.com/llvm/llvm-project/pull/141423. This pull request reapplies the previously reverted changes and includes the fix, which has been tested locally following the steps at https://github.com/google/sanitizers/wiki/SanitizerBotReproduceBuild. Note: the fix is included as part of the second commit
