perfetto: The simplest main with perfetto::Tracing::Initialize() failed under ASAN

Perfetto v24.2, Ubuntu clang version 13.0.0-2.

Code sample:

#include <perfetto.h>
#include <chrono>
#include <thread>

PERFETTO_DEFINE_CATEGORIES(perfetto::Category("trace_category").SetDescription(""));
PERFETTO_TRACK_EVENT_STATIC_STORAGE();

int main(int argc, char** argv) {
  (void)argc; (void)argv;
  perfetto::TracingInitArgs args;
  args.backends |= perfetto::kSystemBackend;
  perfetto::Tracing::Initialize(args);
  // perfetto::TrackEvent::Register();
  std::this_thread::sleep_for(std::chrono::milliseconds(100));
  perfetto::TrackEvent::Flush();
  return 0;
}

This code do nothing. It doesn’t post any user-defined trace events. Failure probability depends on std::this_thread::sleep_for. Zero delay or no delay dramatically decrease failure probability. It fails with or without perfetto::TrackEvent::Register(), perfetto::TrackEvent::Flush().
