It was a fresh checkout from Github master from a few minutes ago. I have
modified the main CMakeLists.txt and added /bigobj, as mentioned in the
error message, to CMAKE_CXX_FLAGS for MSVC and now the same code seems to
build fine,so that doesn't look like a corrupted file. I was building a
debug build when I have got that error, not sure whether it has any

I have yet to see whether the extra flag will have any runtime consequences.
