debugging programs that use stl containers

[Craveiro, Marco]

Hello Everyone,

I'm not sure if this is the right forum, so if it isn't please let me know. 
I'm a Unix / c++ apprentice and i've done a little project that I now need
to debug. 
unfortunately, I get lots of detailed information about the stl container's
definition (map)
but none about its contents. And I can't use the []  operator as well. 
(i.e., print foo ["bar"] doesnt work). Is there any way I can see the
contents 
of an stl container in gdb?

thanks for your time,

Marco.
