The executables I am currently working on are 223 Mb and 341 Mb with -g, and these are smaller than some others I have to deal with. The test/debug/recompile loop I spend much of my life in lately is dominated by link time. The link time is strongly affected by the size of the debug information. So it's not the cost of the disk space, that's relatively cheap; it's the time increase caused by reading, writing, and processing more data. Now, it might turn out that adding additional dwarf records for every single declaration won't significantly increase the size of the debug information. But it is a consideration.
