Using the latest nightly (and the latest Clangd plugin with the -2 suffix released by Pecan) and Win7 pro, I got the "black screen of death" in the editor panel (fully black) and then a crash.
Attached the related RPT file.
Moreover why are you still using DrMingw 0.9.1? It is a very old version, 0.9.7 is already available with impovements....
