  Where can I find source code of fast formula computing Pi using GMP?
  How to ensure that all digits are correct?
  I found million digits in Gutenberg project and million digit file from
  angio.net. Gutenberg has 20% more than million, because it end on
  ...5779458151

Ensuring correctness is harder.  Using two different programs+algorithms
will help even if the same GMP library is used in the background.
