  branches/5.1: Bug#43203: Overflow from auto incrementing causes server segv
  It was not a SIGSEGV but an assertion failure. The assertion was checking
  the invariant that *first_value passed in by MySQL doesn't contain a value
  that is greater than the max value for that type. The assertion has been
  changed to a check and if the value is greater than the max we report a
  generic AUTOINC failure.
