I'm using Ubuntu 12.04 x86_64 and the statistical profiler is not
returning a report with the procedures called during the execution of a
thunk.
The package installed through the PPA (using apt-get) was
`5.3.1-20121108~precise'.
I've attached a test program at the bottom of this message.
When the program is run using `racket --no-jit ...', a report is
printed, with the procedures called, but when I run it using `racket
...', no procedure is listed.

I'm suspicious of the package because I can get a report using the JIT
if I compile Racket from the git repository using the tag v5.3 and tag
v5.3.1 and also with the released source distribution v5.3.1 from the
website.
;;; fib-profile.rkt

(+ (fib (- n 1)) (fib (- n 2)))))

(thunk (fib 38))
#:repeat 4)
