No using ELF data - the symbols available in. My understanding is that the software distributed by RPM these days (since circa 2003) default to having all of the symbol information stripped and distributed in a separate debuginfo package.
To wit:
nm /bin/ls nm: /bin/ls: no symbols
I believe that to get any sort of stack trace out of /bin/ls one would need to first load the symbols from the coreutils-debuginfo package.

I'm not talking about debug symbols but rather function entry points defined in any shared object: $ nm /lib/libc.so.6 nm: /lib/libc.so.6: no symbols $ nm -D /lib/libc.so.6 ... 00000000000864b0 W wcstod_l 0000000000083770 T wcstof 000000000008ace0 W wcstof_l 0000000000040810 T wcstoimax 0000000000081e80 T wcstok 00000000000836b0 T wcstol 0000000000083bf0 W wcstol_l ...
