Clang insists on emitting a movt/movw pair into the function pro/epilogues to load the stack protector reference value from memory, and this movt/movw pair may turn out non-consecutively in the instruction stream.
The resulting symbol reference cannot be fixed up by GenFw, as PE/COFF always treats movt/movw as a pair, and the ELF-to-PE conversion will therefore fail.
Just disable the stack protector when using CLANGDWARF.
