Debugging 64bit code with gdb and ddd in AIX

I'm trying to use the GDB debugger and DDD to debug 64bit code. It seems that the AIX toolkit gdb version 6.0 works with 64bit code. But the ddd tool when running gdb gives the following errors :

Starting program: <my binary> <my params>
warning: "": not in executable format: There is an input or output error..

Why the warning?
How to work around?

Version 6.8 of gdb does recognize the xcoff-64 but it doesn't handle the thread breakpoints.

You were right to post here, but most of the audience here are system administrators. I have noticed that many software development qestions go unanswered in the past. Therefore I'm going to transfer this to the software development forum where it hopefully will be answered more likely.

Please contact me if you want the thread to stay in the AIX forum nonetheless.
