// XFAIL: target-windows

// Tests that LLDB correctly parses global symbols
// starting with 'O'. On some platforms (e.g., Darwin)
// C-symbols are prefixed with a '_'. The LLDB Macho-O
// parses handles Objective-C metadata symbols starting
// with '_OBJC' specially. This test ensures that we don't
// lose track of regular global symbols with a '_O' prefix
// in this.
