Your CI seems incomplete. :-)

[pdimov]

Now that this has been merged to master, it breaks the master build of Boost as well.

[apolukhin]

Ouch. Fixing that...

[apolukhin]

Should be fixed in develop and master now

[pdimov]

Isn't, although the errors are different this time. :-)

on Windows.

As I said you need Mac/Windows CI. :-)

[apolukhin]

There is a windows CI :)

The failure is about something different. The library should not build at all at Windows, but it does. Looks like some error in my Jamfile, some b2 commands trigger the build

[pdimov]

I see nothing in the build/Jamfile that would prevent the library from building on Windows.

[apolukhin]

Oh, it does not build in tests because the tests for that particular library are disabled on Windows. However, that does not prevents from building the library itself.

My fault, fix is coming...
