Normally the hist entry's srcline and/or srcfile is set during sorting.
However sometime it's possible to a hist entry's srcline is not set yet
after the sorting. This is because the entry is so unique and other
sort keys already make it distinct. Then the srcline/file sort didn't
have a chance to be called during the sorting. In that case it has NULL
srcline/srcfile field and shows nothing.
Before:
$ perf report -s comm,sym,srcline
...
