I get a segfault when starting a 3.6.3-rc0 config server on macOS [tim@jazzstep dbs]$ mkdir cfg [tim@jazzstep dbs]$ /tmp/mms-automation/test/versions/mongodb-osx-ssl-x86_64-3.6.3-rc0/bin/mongod --replSet csrs --configsvr --dbpath cfg --logpath cfg/mongod.log Segmentation fault: 11 Logfile with stacktrace attached.

We'll need to revisit it and re-commit with a fix, but we don't want this to hold up the release of 3.6.3 (or release 3.6.3 with this crash). milkie commented on Fri, 16 Feb 2018 20:57:57 +0000: A commit has been identified as the cause; will determine next steps shortly. commit cad0d35091f98b5c2bb37765861841844bd9e16d
1. Create dbpath: mkdir cfg 2. Start a config server: mongod --replSet csrs --configsvr --dbpath cfg --logpath cfg/mongod.log
