[Zhaojun-Liu]

Issue description: One test fails after runtest in MSVC. Could you please take a look?

Reproduce steps:

1. git clone ​https://github.com/boostorg/boost.git F:\gitP\boostorg\boost
2. git -C "F:\gitP\boostorg\boost" submodule update --init --recursive
3. open a VS 2019 x86 command prompt and go to F:\gitP\boostorg\boost
4. set CL=/permissive-
5. .\b2 -j16 variant=release --build-dir=..\out\x86rel libs\wave\test

[jefftrull]

Thank you for the excellent bug report. It may some time before we get to it, unfortunately.

[jefftrull]

I've reproduced this, but I'm not sure yet what is happening and particularly why /permissive- makes a difference. Investigating.

[jefftrull]

Disabling "two-phase conformance" (a new MSVC feature) with /Zc:twoPhase- makes this work again. Still investigating.

[jefftrull]

The develop branch now contains a fix for this issue. Please reopen if you encounter any problems.

[Zhaojun-Liu]

Ok. Thank you, I'll verify this issue in a follow-up test.
