--- Comment #5 from Matt Godbolt <matt at godbolt dot org> --- > And can you please test a more recent compiler (gcc-10 or gcc-11)? Unfortunately not easily; we have a whole ecosystem of libraries we link in (not attached here). If we get any more time we'll try and update, but we've spent all the time debugging that we can afford for now. Sorry.
