Tested this with both Features="collision-protect stricter" and without. Compiles like a charm. This has been ~ arch keyworded for three months now, and is ready to be marked stable. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Correction: 5 months without a single bug. This stabilization is needed by bug #115177
Thanks for testing, please just add it as a comment on the existing bugs in the future :) Also, how you worded this implies you only tested to see if it compiled, not if it actually worked, which should be checked as well.
