+Gitlab bug preventing reporting of GHC bug
+
+# The bug-reporting bug
+
+I ran into a GHC bug, and was told to go to [this page](https://gitlab.haskell.org/ghc/ghc/wikis/report-a-bug) to report it. That one said I should go to [this one](https://gitlab.haskell.org/ghc/ghc/wikis/trac/ghc/register) to "register an account on this Trac" (which is gibberish to me). I followed the link and tried to fill it out (see below), but every time I click "create page" I am taken to a page with a big orange image of what might be a cubist fox's head, which says
+
+```
+500
+Whoops, something went wrong on our end.
+Try refreshing the page, or going back and attempting the action again.
+
+Please contact your GitLab administrator if this problem persists."
+```

+
+## Title
+
+trac/ghc/register ghc panic, "impossible" happened while running tests, failed to load shared object
+
+## Content
+
+Here's the message I got from within GHCI. (The first line is the command, `tests`, that I had just run.)
+
+```
+> tests
+ghc: panic! (the 'impossible' happened)
+  (GHC version 8.6.3 for x86_64-unknown-linux):
+        Loading temp shared object failed: /tmp/user/1000/ghc24072_0/libghc_36.so: undefined symbol: RsltziRValid_validRslt_closure
+
+Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
+```
+
+Here's [the commit of the code](https://github.com/JeffreyBenjaminBrown/hode/tree/d849526a540cbd9119d7cfb05c4762f63e5d03dc) I was working on when this happened.
+
+I keep the test suite in the main body of code, so that I can run it from within GHCI. That's what I was doing when it happened.
+
+I've kept a copy of that shared object (I'm assuming that's what .so stands for) but when I try to attach it I get a "500 Internal Server Error" message.
