Build process stops; no error message

My current project works fine in the editor. It compiles and runs the current scene. I wanted to build (via the build and run option), but it fails to build the current scene. It just stops with a beep. There is no error message or any other indicators for why it stopped compiling.

I have no idea what to do next besides submitting a bug report (done).

Can anyone let me know what the likely problems are?

I figured it out. I created two files (in different directories; both empty) for future expansion. Unfortunately, both files were named the same. Apparently, that caused the conflict…
