--- Comment #1 from Basile B. <b2.t...@gmx.com> --- Note that the issue is not related to piping the source code. The problem was observed for the first time when trying to build dcd with -m64. It was also much less random by the way. to verify if this is fixed: ``` git clone https://www.github.com/dlang-community/dcd git submodule update --init --recursive set MFLAGS=-m64 build.bat ``` Other detail: last time before today that I was on win my dmd was at 2.082 so this could be a 2.083 regression as well. --
