Hi all,

Boost failed to run libs\python\test on x64 and x86 on release and debug configuration with MSVC on windows. it can be reproduced on c368e0b on master branch. Could you please help look at this issue?

Environment: VS 2019 + Windows Server 2019

Repro steps:

1. git clone https://github.com/boostorg/boost.git F:\gitP
2. cd F:\gitP\boostorg\boost
3. .\bootstrap 2>&1
4. .\b2 headers variant=debug --build-dir=F:\gitP\boostorg\boost\out\amd64rel address-model=64 2>&1
5. .\b2 variant=debug --build-dir=F:\gitP\boostorg\boost\out\amd64rel address-model=64 2>&1
6. set CL=/D_SILENCE_EXPERIMENTAL_FILESYSTEM_DEPRECATION_WARNING
7. set OPENSSL_ROOT=F:\tools\OpenSSL\64
8. set path=F:\tools\OpenSSL\64\bin
9. set path=C:\Python\Python27
10. .\b2 -j16 variant=debug --build-dir=F:\gitP\boostorg\boost\out\amd64rel libs\python\test 2>&1
