/bigobj (Increase Number of Sections in .obj file)
/bigobj increases the number of sections that an object file can contain.
By default, an object file can hold up to 65,536 (2^16) addressable sections. /bigobj increases that address capacity to 4,294,967,296 (2^32).
Most modules will never generate an .obj file that contains more than 65,536 sections. However, machine generated code, or code that makes heavy use of template libraries may require .obj files that can hold more sections.
An .obj file produced with /bigobj can only be consumed by a linker that shipped in Visual C++ 2005 (or later). Linkers that shipped prior to Visual C++ 2005 cannot read .obj files that were produced with /bigobj.
