This is now more of an FYI, as I can disable random and get the build I 
need.

boost 1_69_0
clang version 8.0.0 (trunk 349323)
Windows 10

Build command:
./b2 toolset=clang-win runtime-link=shared link=shared 
define=BOOST_TEST_DYN_LINK cxxflags='-DBOOST_THREAD_DONT_USE_CHRONO' 
linkflags='-DBOOST_THREAD_DONT_USE_CHRONO' address-model=64 
threading=multi variant=release -s NO_COMPRESSION=1 --layout=system 
--abbreviate-paths -j2 --without-python --without-mpi --without-log 
--without-math  stage

The first error is

The build succeeds upon adding --without-random to the build invocation.

I tried attaching the full log, but then the message was rejected for 
being too large.
