I'm still convinced this is untrue (apart from disk space). Debug
symbols are not part of the executable view. The kernel & loader map
PT_LOAD sections, which do not include the debug symbols. Indeed debug
segments don't have a load address, so the loader won't know where to
put them if it does. Compare and contrast the output of 'readelf
-l' (which shows the program headers - in particular look at the
PT_LOAD sections) and 'readelf -s' (which shows all segments).
If any one can point me to code in the kernel or loader that maps debug
symbol sections I'm sure many would be interested.
