PVS-Studio warning V501 for Chromium

TEST(SharedMemoryTest, MultipleThreads) {
  ...
  int threadcounts[] = { 1, kNumThreads };
  for (size_t i = 0;
       i < sizeof(threadcounts) / sizeof(threadcounts); i++) {
  ...
}

This is what should have been written here: i < sizeof(threadcounts) / sizeof(*threadcounts).

This suspicious code was found in Chromium project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions 'sizeof (threadcounts)' to the left and to the right of the '/' operator. base_unittests shared_memory_unittest.cc 231
