Yea, I suspect something with ccache is going wrong. We have before noticed
problems with ccache on mingw, where it somehow used .o files from the wrong
major versions, despite obviously the input files obviously not supposed to be
matching. I don't know what could cause that...
For now I've cleared the task's cache, but that's clearly not a full fix...
