#9945: Regression test using random number generator incorrectly

 Reporter:  chris.cooper@…    |      Owner:  grafik
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  Regression Testing
  Version:  Boost 1.54.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+--------------------------------
 libs/utility/operators_test.cpp loops 1000 times, running a variety of
 tests on seemingly random values.  However, since the randomizer
 (boost::minstd_rand) is instantiated inside the loop,  it is re-seeded for
 each loop, meaning it runs the test 1000x with the exact same values each
 time.

 The randomizer must be instantiated outside the loop.
