Indeed. By "relocation" I mean that it was built using one stdlib and moved to the system with another one, but I agree that it's more correct to name as stdlib issue rather then relocation issue. I tried to link with libc++.so that generated by v8 build, though, no luck with it for some reason. For now using is_clang=false works fine, apart that it increases php-v8 tests run time with valgrind enabled significantly.
