Dereferencing pointers on "backtrace full"

Dereferencing pointers on "backtrace full"

[Shadowcat]

Is there any way for GDB to do this?  I'd like to be able to type "bt 
full" and get, at a quick glance, the exact values of all the pointers 
referenced by local variables.  It would make things a lot easier in a 
lot of situations.

Thanks for any help you can give!

There is no built-in way to do this that I know of.

You might be able to do it using Python scripting, in CVS GDB.  I am not
certain... we have a "backtrace" written purely in Python on the archer
python branch, but offhand I don't recall whether all the infrastructure
bits needed for this have been pushed upstream yet.

Using the old-style gdb scripting language:
while (1)
   info locals
   up
end

This doesn't dereference pointers.
