Changes from RC1:
* Fix a recently introduced bug in Boost.Asio where it would read from uninitialized memory.

As always, the release managers would appreciate it if you download the
candidate of your choice and give building it a try. Please report both
success and failure, and anything else that is noteworthy.

I was able to successfully build the RC2 libraries on Mac OS 10.15 using:
Apple clang version 11.0.3 (clang-1103.0.32.62) using C++03/11/14/17/2a

And with a recent ToT clang using C++03/11/14/17/2a
