Hi!Is there any support of D2 in gdb 7.2 ?

As Steven has already stated, you need to use 'b _Dmain', then it will work as expected. When you do 'b main' it breaks at the runtime main() function, which handles things like uncaught exceptions, runtime initialisation, static constructors and destructors, unittest running etc. As the version of druntime that dmd is linking to has no debugging information, you end up with the above issues.
Hope this helps. -- Robert http://octarineparrot.com/
