Hey all, I wish I remembered it sooner. But ehh yeah, cortex-m-rt is very much broken.
We thought there was something with our code 😅
Combined we've been looking for a couple of hours.

There's already a PR for the next release: https://github.com/rust-embedded/cortex-m/pull/533
Might I suggest we actually do the release?

In any case, we should yank the 0.7.4 version of cortex-m-rt
