D2 and gdb

[vnm]

Hi!

Is there any support of D2 in gdb 7.2 ?

Little example to clarify my question:

------------------------------------------------------------

// file main.d
int glVar = 0xAAAAAAAA;

void main()
{
  glVar = 0xBBBBBBBB;
}

------------------------------------------------------------

I compiled it using command "dmd -gc -debug main.d";
then I load it to gdb and trying to debug application:

------------------------------------------------------------

vnm at vnm:~/proj/d_gdb_test$ gdb main

Why gdb can't show line information and why it shows symbols in mangled 
form ? Is this software issues or I'm doing something wrong ?
AFAIK, gdb 7.2 integrated some patch for D support (including symbols 
demangling feature). This patch was D1 only ?
