Clone https://github.com/madskristensen/WebEssentials2015/commit/d946b8b44aa0bf3a53b67c6a7d0922a458ca12bb (the version of WE shouldn't matter at all, unless I manage to fix F12)\r\n 2. Run\r\n 3. Open a Markdown file containing a C# code block:\r\n\r\n        ```C#\r\n        int x = x = 0;\r\n        ```\r\n 3. Set Break on unhandled exceptions\r\n 4. Select any identifier defined in the code block and press F12\r\n 5. Roslyn will throw an ArgumentException (the buffer is somehow getting a StaticTextContainer; I'll file that issue after I manage to debug it)\r\n 6. Load symbols for the top two stack frames (EditorFeatures.Text & VS.LangServices) from DotPeek\r\n 7. Launch a third copy of VS, set Break On Exceptions, and attach to the original (debugger) copy\r\n 8. Open either of the top two stack frames\r\n 9. The debugger will crash with a null reference in vsdebugeng.manimpl.dll\r\n 10. Close the exception dialog in the third copy\r\n 11. Watch it crash too"},"comment":{"url":"https://api.github.com/repos/dotnet/roslyn/issues/comments/73812302","html_url":"https://github.com/dotnet/roslyn/issues/39#issuecomment-73812302","issue_url":"https://api.github.com/repos/dotnet/roslyn/issues/39","id":73812302,"user":{"login":"ManishJayaswal","id":9527491,"avatar_url":"https://avatars.githubusercontent.com/u/9527491?v=3","gravatar_id":"","url":"https://api.github.com/users/ManishJayaswal","html_url":"https://github.com/ManishJayaswal","followers_url":"https://api.github.com/users/ManishJayaswal/followers","following_url":"https://api.github.com/users/ManishJayaswal/following{/other_user}","gists_url":"https://api.github.com/users/ManishJayaswal/gists{/gist_id}","starred_url":"https://api.github.com/users/ManishJayaswal/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ManishJayaswal/subscriptions","organizations_url":"https://api.github.com/users/ManishJayaswal/orgs","repos_url":"https://api.github.com/users/ManishJayaswal/repos","events_url":"https://api.github.com/users/ManishJayaswal/events{/privacy}","received_events_url":"https://api.github.com/users/ManishJayaswal/received_events","type":"User","site_admin":false},"created_at":"2015-02-11T00:12:49Z","updated_at":"2015-02-11T00:12:49Z","body":"The fix was on VS side of debugger.
