--- Comment #8 from Rémi Ducceschi <remi.ducceschi at gmail dot com> --- It seems to be fixed on the last version available on wandbox.org (gcc HEAD 9.0.1 201904): https://wandbox.org/permlink/Tu4T8jEXDDtDw0OS Though it doesn't work on any other versions (8.3.0...). Any chance to see the fix in the 8 branch? Anyway, thanks a lot :)
