Instead of hunting down the issue I set: v8_enable_webassembly=false That got rid of the above undefined symbol issues. If you need WASM then I think it is something generating libc++ specific code (ie: std::__Cr::atomic<bool>) since the MS c++ lib doesn't use "__Cr" namespace. Not 100% sure of this since I got tired of chasing it down and just took the sledgehammer to WASM.
BTW, I am build V8 12.8.374.21 (from tag). Hope this helps. Laters, SLDR (Stephen L.
