yeah, gcc has the "reason" of needing vec to work with gc.  gdb might
want the perf advantage in auto_vec of using stack storage for short
arrays, but that's the only reason I can see to not use std::vector
outside of heap data structures.  In the heap I think  the auto_vec
layout is better than std::vector, but again just a perf question.
