Change #262845

Comments

Make other chunk allocation improvements.
Make the chunk size an unary macro rather than a variable.  Make chunk
index unsigned.  Introduce a helper function with additional validation
and a more useful error message to initialise the current chunk.  Use
the latter in initchunks() to start the data allocations in chunk 0
rather than chunk 1.

In newchunk_nolongjmp(), if the requested data size is too big for both
the current chunk and the next chunk, there is no point in having the
side effect of initialising the next chunk, so in this case just return
an error early.  Ibid., lose the pointer to the current chunk because
using two ways to acess the same data creates a space for an error.
Ibid., use the new helper function and make another error message more
useful.
