libc++ 18+ requires element types of std::deque/std::queue to be
complete at the point of declaration, this is exposed when compiling apt
using libc++ headers.
In solver3.h, Solver::Var was only forward-declared when the
propQ and discoverQ queues were declared, leading to a build failure:
error: invalid application of 'sizeof' to an incomplete type 'APT::Solver::Var'
A potential workaround patch for apt to overcome this is here
https://salsa.debian.org/apt-team/apt/-/merge_requests/511/diffs?commit_id=7c68412e36434786cdc75e514a56350ab2c38caa
but this patch perhaps should not be required.
