query stack during panic:
#0 [type_of] computing type of `B`
#1 [check_well_formed] checking that `B` is well-formed
... and 2 other queries... use `env RUST_BACKTRACE=1` to see the full query stack
error: aborting due to 1 previous error; 1 warning emitted
Code
Maybe related to #136138. Similarly, if we remove the first line
#!feature(min_generic_const_args)], the panic disappears.However, the stack trace is totally different.
