Thanks Jakob,
You are right, I do use `use_custom_libcxx = false`, I just tested without
it and it compiled successfully so I guess this is really the issue.
Here is the rest of my compilation options (if its still relevant):
`v8_monolithic=true v8_use_external_startup_data=false
treat_warnings_as_errors=false is_component_build=false use_custom_libcxx =
false`.
Thanks,
Meir
