Subject: [Boost-users] Boost 1.60.0 breaks Boost.Log formatter on MSVC11
From: Robert Rumpf (robert.rumpf_at_[hidden])

I’ve been happily using Boost.Log (and much of the rest of Boost) for
years, but on upgrading to 1.60, I find that I get runtime errors on MSVC

I’ve tracked the problem back to a simple representative example (as
provided with the Boost.Log library):

The problematic portion of the example is the usage of character arrays
when setting up the formatter, specifically:

<< ": <"

<< "> "

The code compiles fine but then throws an exception at runtime, seemingly
due to uninitialized data. Removing the strings in the formatter
configuration makes the error disappear. I would guess that it has
something to do with xvalues going into the formatter unintentionally, but
this code has functioned fine on prior versions of Boost 1.59-1.54, and I
can find nothing in the release notes that points me at where the problem
might be.

I am compiling with BOOST_SPIRIT_USE_PHOENIX_V3.

Before I start doing lots of diffs, has anyone else experienced this
problem, and is there any known solution or workaround?

Thanks for all of the excellent work and support,
