https://issues.dlang.org/show_bug.cgi?id=14480 --- Comment #15 from ponce alil...@gmail.com --- Have you tried gdc/ldc? I'm sorry I've tried it all and this is way beyond me. GDC doesn't build my code on Windows (bug reported). LDC doesn't build my code either (bugs reported). I've tried to build LDC because I was told to, and LLVM itself doesn't build here despite following the instructions. Have you tried to use dust mite? I also haven't tried to reduce it more because this bug has already been reduced by Vladimir. I guess isolating the bezier subdivision function would work though. It's not easy because the program I work on isn't standalone. I'm pretty hopeful the reduced case by Vladimir will fix other cases here. --
