ICE while compiling redis-0.16.0

[WaffleLapkin]

Code

CI in teloxide project failed with ICE:

• PR: Provide new url for tg-vimhelpbot teloxide/teloxide#335
• failed CI: https://github.com/teloxide/teloxide/pull/335/checks?check_run_id=1802208287

I don't have much time to research this, so I'm providing the error as is.
