This is what the doc says about /bigobj:
https://msdn.microsoft.com/en-us/library/ms173499.aspx

My suspicion is that as that optimizer code works over all possible OSG
nodes, it is possible it is trying to instantiate ton of templates (e.g.
osg::ref_ptr<>), pushing the number of sections over 64k in my particular
case, with my set of self-compiled dependencies.

It seems that adding /bigobj should be safe, only compilers older than MSVC
2005 wouldn't be able to deal with such object files - which is a
non-issue, because one cannot really mix C++ object files/libs between MSVC
versions safely anyway.
