Benefits of -traceback flag

Benefits of -traceback flag

I've found this flag that is supposed to "Generate extra information in the object file that allows the display of source file traceback
information at run time when a severe error occurs."

My question is who uses this info i.e., when will I see the benefit of turning this flag on? (Is it used by the execinfo functions?)

I run Itanium/Linux.

Also The manual states that the -debug inline_debug_info also generates "extra traceback information". Just compiling yields different sized binaries so I know its not just a subset. What is the difference (between -traceback and the extra traceback information in -debug inline_debug_info)?
