I've never seen any problems once a file has been stripped.

Symbols are used for debugging and relocating purpouses, and any executable file could live without them.

Having said that, the --strip-debug option we use to strip is quite harmless under normal circumstances. It doesn't strip anything vital from the files. It also is quite safe to use --strip-all on regular programs (don't use that on libraries - they will be destroyed), but it's not as safe, and the space you gain is not all that much. But if you're tight on disk space every little bit helps, so decide for yourself. Please refer to the strip man page for other strip options you can use. The general idea is to not run strip on libraries (other than --strip-debug), just to be on the safe side.

So, new proposed patch:

strip_debug()
{
    echo "removing debug symbols from binaries"
    find ./ -type f -iregex ".*\.[^a]" -exec strip -p --strip-all '{}' ';' 1> /dev/null 2>/dev/null 
    find ./ -type f -iregex ".*\.[a]" -exec strip -p --strip-debug '{}' ';' 1> /dev/null 2>/dev/null 
}

Shared objetcs (.so) are always stripped (at least, on debian)
