PropGCC compilation question re .debug items

I am using sprintf successfully but am very curious as to the contents of the report from propeller-elf-size -A -d -t %target%-%memmodel%.elf. If I don't use sprintf the "Total" is ~25K. The reported total with sprintf is much larger and is obviously not being actually loaded to the Prop. I suppose adding the debug symbols is a GCC switch that was used to compile the library? Thanks for any feedback on this.

Sections marked LOAD are the only ones actually loaded to the Propeller. Ones marked ALLOC define space that is reserved in memory, but which doesn't need to be loaded (this is like the "res" directive in Spin). Ones that are neither ALLOC nor LOAD are purely for internal use of the gcc tools.
