int LoadOperations(....)
{
  ....
  disk_cache::BackendImpl* cache = new disk_cache::BackendImpl(
    path, 0xf, cache_thread->message_loop_proxy().get(), NULL);
  if (!cache || !cache->SetMaxSize(0x100000))
    return GENERIC;
  ....
}

This suspicious code was found in Chromium project by PVS-Studio static code analyzer.
Warning message is:
V668 There is no sense in testing the 'cache' pointer against null, as the memory was allocated using the 'new' operator. The exception will be generated in the case of memory allocation error. crash_cache.cc 269
