This is the first function that differs. Maybe there are others, I didn't actually check.

I can now confirm it's 32-bits only. And it seems to be a regression between clang 8.0 and 9.0 for the same reason as given in bug 1596283.
One variant of the function is (from https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/dOip0GF7S-GtQe6gfJG2UQ/runs/0/artifacts/public/build/target.tar.bz2):
For reference that was https://treeherder.mozilla.org/#/jobs?repo=try&revision=8a1b43ec5b996d88c3987764be319b48d58212ee&group_state=expanded&selectedJob=276151651.
Another variant is (from https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/Arhv48TBQ3GF86DB04dt2Q/runs/0/artifacts/public/build/target.tar.bz2):

The current perma bustage is unfortunately unrelated to this bug... it's a different difference, and it's hidden by the fact that we don't have a copy of all the generated files in the build :( I'll file a separate bug about that, and when that lands, we should see the linux32g build fail with a more useful error.
