Thanks. I'm still thinking about decl_line. It's not a value associated with a specific PC. It feels a bit weird to return it attached to a PC. On the other hand it's admittedly less efficient to require the caller to look up the function name to get the decl_line (in libbacktrace this would be backtrace_syminfo to get the initial PC and backtrace_pcinfo to get the line number of that PC; this could of course be cached).
