Fix UB in ExternalWorkload.actor.cpp #2410

Open atn34 opened 4 years ago

atn34 commented 4 years ago 
/home/anoyes/workspace/foundationdb/fdbserver/workloads/ExternalWorkload.actor.cpp:159:21: runtime error: member call on address 0x00001b87c7b0 which does not point to an object of type 'FDBWorkload'

To repro, build with cmake with -DUSE_UBSAN=1 and run ctest -V -R SimpleExternal

FWIW removing -fvisibility=hidden from the compiler flags does not seem to fix this. I think this might have to do with the way we use dlopen?
