>   Internal compiler error: LFS error for "/Users/jfb/s/llvmm/debug/tools/clang/test/Index/Output/pch-from-libclang.c.tmp.mcp/14EC4PG1UTVLY/modules.idx"failed to create unique file /Users/jfb/s/llvmm/debug/tools/clang/test/Index/Output/pch-from-libclang.c.tmp.mcp/14EC4PG1UTVLY/modules.idx.lock-0ae18733: No such file or directory

yay! I really like how it looks now, thanks for pushing on this.

> `clang -fmodules -fmodules-cache-path=...` is supposed to create the directory for the cache path, including the parent directories, AFAIK. If this doesn't happen it is a behavior change (and undesirable IMO).

Is `c-index-test` invoking `clang` or do we just have a similar interface? Perhaps it's not doing it right (haven't seen this problem happening directly while invoking clang). Should `-fallow-pch-with-compiler-errors` be considered somehow here?
