Hello, 

I'm trying to update from boost 1.61 to 1.62 on msvc for conda and encountered this error:

Full logs are available here: https://ci.appveyor.com/project/conda-forge/boost-feedstock/build/1.0.36 

I've got the same error for vc9, vc10 and vc14 for both 32 and 64bits. 

I configure with the exact same script I used for 1.61, here's the configure part: 
call bootstrap.bat 
.\b2 install ^ 
--build-dir=buildboost ^ 
--prefix=%LIBRARY_PREFIX% ^ 
toolset=msvc-%VSTRING%.0 ^ 
address-model=%ARCH% ^ 
variant=release ^ 
threading=multi ^ 
link=static,shared ^ 
-j%CPU_COUNT% ^ 
-s ZLIB_INCLUDE="%LIBRARY_INC%" ^ 
-s ZLIB_LIBPATH="%LIBRARY_LIB%" 
It can be seen there: https://github.com/conda-forge/boost-feedstock/blob/master/recipe/bld.bat 

I've not seen it reported in the trac tickets, did someone get the same error ?
