I assume this is addressed to me. I had tried reinstalling msys2 from scratch in order to build Kicad numerous times according the "easy way" instructions and another tool winmakekicad. I had also built OCE from scratch. I had (I thought) previously tried to build Kicad the not easy way and failed previously. Reinstalling msys2 takes time and has the potential for screwing up other things I am doing. Because I figured the most recent "not easy way" build instructions would fail I ran them without reinstalling Msys2 fresh. This make for release and debug versions worked. As such, it may be that the history of my Msys installation or some other thing like having built OCE may have enabled the build to work. I just thought I'd mention it in case it mattered. So, long story short my Msys2 is a relatively recent (past few weeks version), updated with pacman -Syuu a few times and not a fresh, virgin install. Does that make sense?
