Re: use / handling of debug information for structures

[Roul Oldenburger]

Thanks for this info,

so DDD more or less 'only' acts as a GUI set on top of a debugger...

someone from the gdb maillist already told me gdb gets the information I 
am looking for from the .stabstr section of the debug information part 
in the executable. This seems to be the same way objdump does it.

Thanks for the help
