Issue description:
We build and run test for boost and we found one tests failed to run after boost submodule log updated from b22211 to 1138b4 boostorg/log@e575e40
Could you please take a look?

Reproduce steps:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git D:\Boost\src
2. open a VS 2017 x86 command prompt and browse to D:\Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\Release --address-model=32
5. .\b2 variant=release --build-dir=..\out\Release --address-model=32
6. .\b2 -j4 variant=release --build-dir=..\out\x86rel libs\log\test

log_x86_test_60.log
