5.7.3 Heap allocation
Heap allocation supports deallocation of allocated memory in any
order. Dictionary allocation is not affected by it (i.e., it does not
end a contiguous region). In Gforth, these words are implemented using
the standard C library calls malloc(), free() and resize().
The memory region produced by one invocation of allocate or
resize is internally contiguous. There is no contiguity between
such a region and any other region (including others allocated from the
heap).
