So I'm guessing this might be a Visual Studio issue. Edward - do you
happen to know which version of VS2019 you're running?
I am running VS2019 16.10.3.
Hi Edward, there's been a development here after I flagged this up to
Microsoft....
I sent them a small test project and it seems that for VS2019 16.11.0
the problem only happens for an x86 build (if I build as x64 it works
okay). Going back to the command line you sent me last week, is there
some way I can adapt it to force an x86 build and alternatively, an x64
build? I could then swap between them and see if there's any difference
here. And it looks like John Maddock might be onto something when he
suggested modifying 'boost/integer/common_factor_rt.hpp'. I'd be happy
to try modifying it temporarily if John can suggest something... Thanks,
John
It is a matter of the command prompt. The vcvars32.bat command prompt is
for an x86 build and the vcvars64.bat is for an x64 build. You are
correct that I tried it for an x64 build. However trying the code for an
x86 build was also successful for me.

I'm wondering if the check for x86 needs to be applied to the
BOOST_MSVC check as well as the intel one?
