I suspect this issue is E-easy, though it's hard to know for sure without more investigation of the code.

If you decide to take this up:

1. Identify which part of the diesel code is causing the ICE
2. Minimize to a small reproduction (MCVE) that triggers the ICE
3. Investigate what's going wrong in rustdoc (probably we mixed up parameter indices or something)
4. Fix the issue
5. Add the MCVE as a test

Feel free to ping me here or on Zulip if you have questions!

Note that the ICE location is slightly different than originally reported since it's been a couple years:
