What this means is, the address that has been passed to free -- that is,
0xf95f6a0 -- is zero-initialised data in libaws-cpp-sdk-core.so and so
has not been allocated on the heap.  It's (the address of) a global
variable in libaws-cpp-sdk-core.so, in other words.

You can poke around more with GDB by rerunning the program on V with
--vgdb-error=0 and following the directions it gives.  GDB will stop at
the error (at all errors) and you can examine the program state at your
leisure.
