But for that you really don't need the symtabs stored in the binaries/shared
libraries, you can just have the backtrace without symbols printed + print
relevant build-ids at the beginning, a script at any time can reconstruct
that into not just the symbol names, but also lineinfo. And the build-ids
will help even if you want to look at further details (.debug_info, source
files).
