Would you mind posting a patch that passes `/*RequiresNullTerminator=*/false` to the function on https://github.com/llvm/llvm-project/blob/main/clang/lib/DependencyScanning/InProcessModuleCache.cpp#L181 and verifying it fixes the issue you're seeing?

Will do, I'm working on how to inject a local patch into our CI-system to check, will post a PR if it works.
