I don't know about this implementation of backtrace(), but such
functions often rummage around in places a portable correct program
never would.  That doesn't mean there's necessarily a problem in this
code, but it's worth inspecting (and adding Valgrind macros to clarify
anything correct-but-odd to V itself).

I'm guessing here, but it may only show up on large code because of the
depth of its stack use.
