It looks as though GDB has attached and you are sitting at the current PC.

No, not necessarily.  You may well be sitting in Redboot also, which GDB
knows nothing about in terms of symbols (since you haven't told it about them
yet).

I don't mean this in any kind of an insulting way, but do you know how to use
GDB for something like this (eg. are you familiar with add-symbol-file)?
Did you build the tests with debugging enabled (eg. -g)?

Again, because there isn't really a ton of info here, I can't just look at it
and say "Ah ha!  The problem is [whatever]"
