I'm still seeing this issue on the latest nightly build. Is it possible this is stuck on develop? Or the rules don't prevent URL from building on msvc-14.0?

I'm pretty sure we updating both develop and master to exclude msvc-14.0:

https://github.com/boostorg/url/blob/develop/meta/explicit-failures- markup.xml#L22 https://github.com/boostorg/url/blob/master/meta/explicit-failures- markup.xml#L22

Maybe we need to do more? I don't know, but the matrix looks like it is being excluded.

You need to fix your Jamfile to disable the library for msvc-14.0, because your current checks do not exclude it. Add <toolset>msvc-14.0:<build>no either somewhere here https://github.com/boostorg/url/blob/643d959e3db8b59cf3f065ec1738cd0197c70b0... or here https://github.com/boostorg/url/blob/643d959e3db8b59cf3f065ec1738cd0197c70b0...
