When we picked up this CL: https://chromium-
review.googlesource.com/c/565567/ we started getting a crash loop from this DCHECK: 
DCHECK(g_cache.Get().config);
https://cs.chromium.org/chromium/src/components/os_crypt/os_crypt_linux.cc?type=cs&sq=package:chromium&l=72

It seems like before we were just getting the default global configuration, but now we need to set one explicitly?

We tried setting a blank confi gin PreMainMessageLoopRun and also in PreMainMessageLoopStart, but neither seemed to help

void CastBrowserMainParts::PreMainMessageLoopRun() {
  std::unique_ptr<os_crypt::Config> os_crypt_config(new os_crypt::Config());
  config->main_thread_runner = content::BrowserThread::GetTaskRunnerForThread(
      content::BrowserThread::UI);
  config->should_use_preference = false;
  OSCrypt::SetConfig(std::move(config));
  ...
}
