--- Comment #6 from zhonghao at pku dot org.cn --- (In reply to Jonathan Wakely from comment #5) > The error message comes from the clang bug report, not from Clang 7.0.0 -- > have you even read the clang report that you're copying?! I attached the original bug report only to help better understand the bug. If you do not need the original bug reports, I will not report the original bug reports any more. I will report only the code and the differences.
