Looks like restart_ is potentially not protected by a mutex.

/usr/local/google/home/ethanmoon/OpenROAD/src/gui/src/renderThread.cpp:150:14

  if (!isRunning()) {
    start(LowPriority);
  } else {
    restart_ = true;
    condition_.wakeOne();
  }

vs

/usr/local/google/home/ethanmoon/OpenROAD/src/gui/src/renderThread.cpp:104:14

    mutex_.lock();
    if (!restart_) {
      condition_.wait(&mutex_);
    }
    restart_ = false;
    mutex_.unlock();

@QuantamHD Thanks for the tip! I'm having a bit of trouble getting it to compile, but compared to the difficulties that @maliberty @AcKoucher and I had with reproducing crashes, TSAN is an enormous improvement!

QuantamHD commented 1 month ago

@oharboe Looks like there are specific packages that provide libclang_rt. You might just need to find where they are on your system and LD_PRELOAD them.

@QuantamHD waiting on your PR for TSAN
