The GNU Debugger's latest version 7.2 add D language support.
In the second point-release for GDB, GNU Debugger version 7.2, D language support is added.
The D programming language is an object-oriented, imperative, multi-paradigm system programming language. It was designed by Walter Bright of Digital Mars as a re-engineering of C++.
Version 1.00 of D was released on Jan. 2, 2007, and the latest stable release, version 1.063, dropped on Aug. 8, 2010.
Until this release of GDB, support for debugging D-specific language features has been limited.
