      1) Build mongod with the following config

      ./buildscripts/scons.py --variables-files=etc/scons/mongodbtoolchain_stable_clang.vars --link-model=static --ninja ICECC=icecc CCACHE=ccache

      2) run mongod with the following config:

      "/home/ubuntu/mongo/build/install/bin/mongod --setParameter enableTestCommands=1 --setParameter 'logComponentVerbosity={'"'"'replication'"'"': {'"'"'rollback'"'"': 2}, '"'"'sharding'"'"': {'"'"'migration'"'"': 2, '"'"'rangeDeleter'"'"': 2}, '"'"'transaction'"'"': 4, '"'"'tenantMigration'"'"': 4}' --setParameter disableLogicalSessionCacheRefresh=true --setParameter coordinateCommitReturnImmediatelyAfterPersistingDecision=false --setParameter transactionLifetimeLimitSeconds=86400 --setParameter maxIndexBuildDrainBatchSize=10 --setParameter testingDiagnosticsEnabled=true --setParameter disableTransitionFromLatestToLastContinuous=false --bpath=/data/db/job0/resmoke --port=27017 --enableMajorityReadConcern=True --storageEngine=wiredTiger --setParameter featureFlagTimeSeriesInSbe=true --setParameter featureFlagTimeseriesAlwaysUseCompressedBuckets=true --setParameter internalQueryFrameworkControl=forceBonsai --setParameter featureFlagCommonQueryFramework=true"

      3) Attach gdb to the process

      4) set a breakpoint at path_utils.cpp:86 then have gdb continue the process (c)

      5) connect to the local mongod instance via mongo and submit the following command 

      db.peter.find()

      When I build the server as a static binary and then debug with the statement:

       

      db.peter.find() 

       

      and set a breakpoint at

       

      b path_utils.cpp:86

       

      gdb crashes with the following error:
