changed milestone to %8.6.1

changed weight to 5

added Tbug Trac import labels

Hmm, this really only happens on ARM?

This only happens on armhf, not armel or arm64.

Would it be possible to try reproducing this with 8.4.3 (or better, master)?

I suspect that this is fixed.

changed milestone to %8.8.1

These won't be addressed in GHC 8.6.

closed

A simple rebuild made it build correctly... Maybe we can close this one?

I would close this one, lets reopen in case somebody still get this issue
