Not out of choice, I assure you.  Were the ability there, I would use it
in a heartbeat.

I need to spend time with AVR-GDB - I've heard good things about it.

For some users, I'm sure this is true.  For others (such as me), an
ability to show a stack trace would be a godsend.  Not everyone is
trying to fit code into an ATtiny or ATmega8!  I specifically chose the
ATmega2560 and added external SRAM so I would not have to worry about
memory resources (as much).  If I could trade SRAM efficiency for a
stack trace, especially as a compile-time option, I would take it!

Eh, such is life.  Since I don't have them, I live without them.  But
just because I don't have stack traces (...and a Lotus Elise ;-) ),
don't believe for a minute that I don't wish for them!
