The C++ DASH template library provides distributed data container for Partitioned Global Address Space (PGAS)-like programming. Because DASH is new and under development no debugger is capable to handle the parallel processes or access/modify container elements in a convenient way. This paper describes how the DASH library has to be extended to interrupt the start-up process to connect a debugger with all started processes and to enable the debugger for accessing and modifying DASH container elements. Furthermore, an GDB extension to output well formatted DASH container information is presented
