It does not reproduce on other OS, MinGW(MSVC is not installed), x86, or without -cov. And if removing unnecessary import statements or unnecessary files, the situation will not be reproduced. Below is a similar link error but the situation seemed different. https://issues.dlang.org/show_bug.cgi?id=20565 --
