Hello.

"p this" should work. I'm 100% sure that I've used that, when debugging C++
programs at work. Which version of gdb are you using? What debug flags did you
use, when compiling?

Try compiling with -gstabs+3 or -gdwarf-2. You'll probably need a recent gdb
(Andris's package of 5.2?) for DWARF-2 to work, but even then there may be
problems. I haven't been able to build libc.a with DWARF-2 debug info, for
instance.

Bye,
