So Clang 9 test failed, but I can't really figure out why and cannot test it without corresponding environment.

rng_test.cpp:19: FAILED:
  CHECK( stats.test_threshold( target_range ) )
with expansion:
  false
with messages:
  Goal: -1.1
  Result: -1.01
  Samples: 100

Looks unrelated to me.

Weird.
Is this Clang 9 test fail just happen randomly?
Pushed an empty commit then all tests passed.

Was a RNG error. I should probably just disable those tests, 99% of the time they break due to RNG alone.

EDIT: I mean those tests that fail all the time, not all tests, of course.
