gdb nearest symbol backtrace

Is there a quick way to get some symbols near the backtrace in a binary without symbols? and show which binary or library it came from?
The ELF file is stripped. Can gdb figure out which libraries were loaded?

eg if i use "layout asm" I can see  _ZdlPv  in the assembler.

$ c++filt _ZdlPv
operator delete(void*)


It's interesting the  _ZdlPv symbol wasn't stripped.

Thanks
