Major - P3 Got a duplicate symbol error for some functions in WaitForMajorityServiceWaitForMajorityService.
This is the SCONS command I had used (note that I did not regenerate Scons after git pulling):
./buildscripts/scons.py --variables-files=etc/scons/mongodbtoolchain_v3_clang.vars --ninja generate-ninja ICECC=icecc CCACHE=ccache
And the Ninja command I invoked:
ninja -j400 install-core
I was at git commit 6c0ac0678f3c159c65c497acf155e964dec43f61 on branch master of mongodb/mongo.
I've also attached my build.ninja file to the ticket.
Here's the full error:
