What's the proper way to debug D programs with GDB?

[Vladimir Panteleev]

Hi all,

I'm trying to debug some random crashes of some D services running on a  
Linux headless server.
I have compiled/linked my programs and Phobos with -g and without -O  
(using DMD), and applied the gdb patches from  
http://dsource.org/projects/gdb-patches/ .
I'm running a script based on  
https://wiki.ubuntu.com/Backtrace#Summary%20in%20script%20form to  
automatically record the backtrace and restart the program.
However, gdb still doesn't print very nice backtraces. Here's an example  
output:


[Thread debugging using libthread_db enabled]

So, what's the proper way to set up D debugging on Linux? Should I just  
look into gdc?
