I suspec= t a latent bug in the diagnostic code. I tried -fmessage-length=3D128, which should work as that is longer than the error line, and does work for this failure, but that causes a different lin= e to fail. Turns out that there is a test that emits a 2.3KB error message. To make the entire testcase work, I need a -fmessage-length value longer than = the longest error message, so the smallest power of 2 that works is -fmessage-length=3D4096 which seems too stupid to submit as a patch.=
