We have been using Boost's graphviz support for several years and have
upgraded through a few versions of Boost with no issues in some long
stable code. However, when we moved to 1.58 our Windows build broke. We
are still using VC2010, with plans to move to 2015 in the
not-too-distant
future. We have not yet tried 1.58 in VC2015.  The error message is very
large but emanates from here:
Can I get (minimal) reproducible code or more detailed error log?
Best,

This stripped down code snip is enough to trigger the error when the 1.58
code is in place and compiles fine when the code from 1.54 is substituted
in the place I indicating initially. This code is not intended to do
anything and I have not run it. I can send the original error message if
you like too. Will send that privately if you want it.
