As already stated in the reply to Axel, this was introduced mostly due to
convenience. To my knowledge there is no way to get a stack trace in
userland that is ready to use in this situation.
There is a GCC bultin _builtin_frame_address() that libunwind uses to
handle exceptions, I guess it is not available in GCC2 but you probably can
achieve the same using the content of ebp.
We already have a recipe and package for libexecinfo which implements
backtrace() and backtrace_info(). It is used by several ports which want
to provide a backtrace on crashes (including webkit in debug mode).
