number of sections exceeded object file format limit
Fatal Error C1128: number of sections exceeded object file format limit : compile with /bigobj. An .obj file exceeded the number of allowable sections, a COFF object file format limitation. Reaching this section limitation can be the result of using /Gy and a debug build; /Gy causes functions to go into their own COMDAT sections. In a debug build, there is a debug info section for each COMDAT function.
