My guess is that there's probably an assertion that's triggering first, but we don't see it since it's an opt build.

Shing, is it possible to run talos locally with --enable-debug builds? If so, it's probably worth reproducing this failure (and others) in that configuration, since that'll give us more to work with, and (hopefully) map to other existing crashtest failures that we have on file.
The crash is gone after update https://treeherder.mozilla.org/#/jobs?repo=try&revision=a5073a9f2756096826ebf3c5cb5596db31207f02
