OK, I reverted that change then. This sounds like a bug in how Clang
generates warnings, as --save-temps shouldn't affect warnings like that.

Yes, it seems both Clang and GCC have such bugs. See https://bugs.llvm.org/show_bug.cgi?id=22949 for Clang and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57201 for GCC. They are easily reproducible, but apparently nobody treats them as high priority.
