Release 12.1 of GDB, the GNU Debugger, is now available.  GDB is
a source-level debugger for Ada, C, C++, Fortran, Go, Rust, and many
other languages.  GDB can target (i.e., debug programs running on)
more than a dozen different processor architectures, and GDB itself

GDB is free (libre) software.

You can download GDB from the GNU FTP server in the directory:
