TYSM @jeanPerier! We really appreciate you taking the time to look into this issue.

The way I reported the issue, invoking two files with `flang -fc1`, was intentional. We use both Clang and Flang as libraries, and this was the most effective way to report the issue in a form that aligns with your typical workflow, where Flang is primarily used as a binary.

Regardless of whether `flang -fc1` is expected to accept multiple input files directly, we believe the fix is still of great value for Flang library users like us.

Again, thanks so much for looking into this @jeanPerier.
