Backtraces for panics didn't have useful method names unless i turned off optimizations. Attempts to debug rustdoc in Visual Studio would just have a blind spot for any source information within librustdoc itself. Profiles would show mangled names for any librustdoc methods.\r\n\r\nEDIT: I should note, a `rustdoc-tool-binary-(hash).pdb` was created, and Visual Studio dutifully found it and loaded it, but it still had all the problems noted above."}}
