terminal output with a bit more context (from the start of my incremental
build, up to the "PLEASE submit a bug report")

I just tried to compile some source code with (accidentally) unbalanced curly
braces, and I got the following resulting output. Filing a bug, as directed by
the error message in my terminal output.

As noted in the run script, it seems I'm using clang version "3.8.0-2ubuntu3
(tags/RELEASE_380/final)"

I'm on Ubuntu 16.04, 64-bit.

My llvm/clang packages are from a sources.list.d file with these contents:
