It would be great to accompany these fixes with regression tests. We have
significant amount of Go code in std lib and tests, but still we discover new
code patterns. Any new compiler functionality (like race detector or coverage
analysis) would benefit from extensive tests.
Does gccgo use tests from the main Go repo? The main repo looks like the best
place for them.
