In my machine the chain seems to consume 256 bytes. That gives ~16 words
per function, a reasonably number (each function uses 2 words for ebp
and return address, plus 3~5 words for saving working registers, plus
its arguments, local variables, and extra working space). Maybe the
release option optmizes your use.
