could we fallback for 0 src lines as well? I'm getting following:
| |--99.85%-- _IO_file_xsputn@@GLIBC_2.2.5 .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
| | __GI___mempcpy .:0
also it would be handy to show raw address (object based).. maybe for -v option?
