My guess is that there may be a parsing bug here - we did refactor our argument parser for things like that recently. In particular, the slash on
'_sqlite3_finalize',\ and the fact that _main is the last item in the list, are the things that make me think it could be parsing-related. Specifically, it could be related to https://github.com/kripken/emscripten/issues/6581#issuecomment-412333543 which is the only known issue I am aware of there. Also helpful to debug this might be to build with EMCC_DEBUG=1 in the env, which will print out the arguments passed, and also the flags passed to LLVM DCE (search for "main", or "-internalize-public-api-list=").
