When using perf report, I don\'t see any symbols for my program, instead I get output like this:
perf report
$ perf record /path/to/racket ints.rkt 10000 $ pe
I got the same problem with perf after overriding the name of my program via prctl(PR_SET_NAME)
prctl(PR_SET_NAME)
As I can see your case is pretty similar:
70.06% ints.rkt [unknown]
Command you have executed (racket) is different from the one perf have seen.
