GDB 7.4 released!
Release 7.4 of GDB, the GNU Debugger, is now available via anonymous
FTP. GDB is a source-level debugger for Ada, C, C++, Objective-C,
Pascal and many other languages. GDB can target (i.e., debug programs
running on) more than a dozen different processor architectures, and GDB
itself can run on most popular GNU/Linux, Unix and Microsoft Windows
You can download GDB from the GNU FTP server in the directory:

There is a web page for GDB at:
That page includes information about GDB mailing lists (an announcement
mailing list, developers discussion lists, etc.), details on how to
access GDB's CVS repository, locations for development snapshots,
preformatted documentation, and links to related information around
the net. We will put errata notes and host-specific tips for this release
on-line as any problems come up. All mailing lists archives are also
browsable via the web.
