Predator and CL could not provide any possible suspects.

Using Code Search for the file, "harf_buzz_shaper.cc" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/7b20499fff2b1a299551ecf8ea8e9fbcf104e1a9%5E%21/third_party/WebKit/Source/platform/fonts/shaping/HarfBuzzShaper.cpp

If you suspect that the result above is incorrect, try re-doing that job on the test case report page.
Hmm, I believe the CL should not make an issue because it just replaced RefPtr with scoped_refptr. If this is a real crash, let me take a look.
