Just to let you know that it's definitely ccache at fault. With ccache commented out of make.conf the compile runs through fine. It took 7 hours, but at least that is better than the over 14 hours that it was taking with WITHOUT_DEBUG_FILES=yes commented out. I guess ccache probably has some kind of issue with the two different versions of clang between 10 and 11. No idea. But I'm now going to install the 11 world/kernel and then the next time I try and update it I'll try it with ccache enabled once again. In theory when it's on the same version of clang it might work fine once again. -- Matt
