This seems to be a known issue with Xcode https://stackoverflow.com/questions/39680320/printing-debugging-libc-stl-with-xcode-lldb
There might be a way to configure Xcode to emit more debug symbols but the best way is probably to develop on Linux in Docker or in a VM On Sep 21, 2018 9:00 PM, "Atri Sharma" <[email protected]> wrote: MacOS High Sierra. If you do a build (/debug, make) and then attach lldb to a test (lldb -- compute_test), then try to access a class's members (e.g. ArrayData's buffers), the error pops up.
