My hypothesis is that this will replicate https://travis-ci.com/rust-lang/miri/jobs/220221687 (so we know which commit range caused it).

The regression landed with rust-lang/rust#63043; the likely cause is rust-lang/rust#62982.

Dang, the log is too long for Travis... but then how can we debug this? :/

My best guess so far is that it has something to do with the find_foreign_static machine hook. That one emulates the existence of __cxa_thread_atexit_impl and maybe using the type there is not the right call?
