I've hit a case where this causes compilation to hang indefinitely (or so it seems; the case earlier compiled in around 2 seconds, and now hasn't finished after at least 7 minutes), with https://martin.st/temp/dvdec-preproc.c compiled with `clang -target x86_64-w64-mingw32 -w -c -O3 dvdec-preproc.c`.
