This is missing the panic message - do you happen to still have it? There should have been more output above "internal compiler error".

[fxdave]

I didn't get the panic message. I couldn't reproduce it.

[jyn514]

query stack during panic:
#0 [predicates_of] computing predicates of std::ops::Deref

Likely a duplicate of #83259.
