Invariant failure in mongod during query planning.

Setup

cd mongo
git checkout 6966674b8ea1367f71ca47e68db8ad424aefd949
python2 buildscripts/scons.py     \
    -j$(nproc)                    \
    --disable-warnings-as-errors  \
    mongo mongod mongos
git checkout visemet/mongodb-rr-experiment
git am ../bf-9864/patches/0001-Remove-enableMajorityReadConcern-option-from-mongod.patch
git checkout 6966674b8ea1367f71ca47e68db8ad424aefd949 -- jstests/sharding/recovering_slaveok.js
git commit -m 'Use version of test from failing commit.'

rm -rf ~/.local/share/rr/*
python2 buildscripts/resmoke.py  \
    -j$(( $(nproc) / 3 ))        \
    --repeatTests=1000           \
    --continueOnFailure          \
    --log=file                   \
    --reportFile=report.json     \
    --rr=chaos                   \
    --suite=sharding_auth        \
    jstests/sharding/recovering_slaveok.js

Results

The 1000 runs were interrupted due to the machine's 200GB disk becoming full after running for approximately 40 hours.
