--- Comment #9 from darkkirb at darkkirb dot de --- I have bisected the fix a bit (I didn't have enough time today to finish it) and i found that the fix has happened in one of the 322 commits between d1540be4d3b4b8ac6d19997539c13d2ca74f65e4 (2018-09-26, broken) and 44257478a8d157f8e0030bb7abe1c3ac91be9302 (2018-10-31, fixed) Hopefully the fix can be applied to the gcc-8_0 branch.
