The bit code file produced by the stage 1 compiler for one of the files in the clang driver is corrupt and causes the linker for stage 2 to crash.

...it could be something like binary size change that caused different code alignment or some such and which triggered a latent memory bug somewhere else. It's already late evening for you now.

...build, so it will take a while longer. I don’t have any other useful information at this point, and I share your puzzlement about how your changes could possibly break the compiler. My only hypothesis is some sort of memory corruption. I will keep you posted.
