In the 1.54.0 release, I noticed that the size of the binaries built with visual studio was more than twice that of the previous releases. For example the msvc-8.0-64 build went from 2GB to 5GB. Upon further investigation, almost all of that increase was in the libboost_log_setup* binaries, which were each in the 100s of MBs.

Does anyone know if there is a reason for this? Is it a configuration error?

Yes, these libraries are expected to be quite large, especially when debug symbols are on.

We're not talking about a bit bigger, these are bigger than all the rest put together.

I did not compare library sizes purposefully, but it is very possible to be the case. If you build the complete version of the library, the resulting binaries are expected to be large. Someone else asked me a similar question on the SF, and the answer is, well, because there is lots of code in there. The setup library is especially big because it contains rather complicated Boost.Spirit parsers for filters and formatters and it instantiates parsed filters and formatters for all fundamental types. Multiply that by the number of character types the library supports.
