And, BTW the stack size is doubled which is not a very good strategy.
With the simplest memory model (one contiguous segment) one can see
that if the array is allocated first at address 0 and then at the
lowest address that can hold it then the base address will keep
increasing. This assumes that there aren't other big data structures
in memory that get collected.

The same issue prompted a change in the implementation of STL in MSVC
7.0. IIRC the grow factor was reduced from 2 to 1.5. In theory to
allow reuse it is sufficient to use a factor less than the golden
ration.
