If I squint a bit I can sort of see how this patch might cause a
failure like that, but I reverted it locally and saw no CodeGen change
in the failing file. I'll try to reproduce it locally today, but my
environments will be pretty approximate (iOS and Debian on ARM). Do
you have access to get artefacts off the builder if that fails?

Cheers.

Tim.
