Because there are platforms that do not ship with gdb. macOS for example ships with lldb these days. lldb is also the debugger of choice for a bunch of languages like Swift that have no gdb support. (The reference Swift implementation is free software.) I'm not sure if Rust only is supported by lldb but I think that may be the case, I would have to check. Perry -- Perry E.
