SBCL statistical profiler warns of undefined function

Question

SBCL 1.3.9 produces the following error when I attempt to run the statistical profiler. Is start-profiling not exported?

* (in-package :cl-user)
* (require :sb-sprof)
* (sb-sprof:with-profiling (:report :flat) (bnb::solve))
; in: SB-SPROF:WITH-PROFILING (:REPORT :FLAT)
;     (SB-SPROF:START-PROFILING :MAX-DEPTH 4611686018427387903 :THREADS
;      (LIST SB-THREAD:*CURRENT-THREAD*))
;
; caught STYLE-WARNING:
;   undefined function: SB-SPROF:START-PROFILING
;
; compilation unit finished
;   Undefined function:
;     SB-SPROF:START-PROFILING
;   caught 1 STYLE-WARNING condition

debugger invoked on a UNDEFINED-FUNCTION in thread
#<THREAD "main thread" RUNNING {100292C913}>:

Type HELP for debugger help, or (SB-EXT:EXIT) to exit from SBCL.

It seems a problem with your distribution. please update to the last SBCL wich is

The most recent version is SBCL 1.3.18, released May 30, 2017

But if you take a look at the sources in github

git log -S start-profiling --source --all

    0.9.18.58:
            Further SB-SPROF improvements.

            * Allocation profiling on gencgc. When the profiler is running in
              allocation profiling mode, the gc will signal profiler ticks
              when new allocation regions are opened.
            * Add :LOOP keyword argument to WITH-PROFILING, to allow specifying
              whether the body should be evaluated repeatedly until the maximum
              sample count is reached.
            * Improve merging of code-components with multiple debug-funs,
              better handling of multiple functions with the same name
            * More documentation
            * Also update the stepper documentation

    0.8.11.20:
            Add SB-SPROF contrib

That funcion was added a lot time ago, so please try the latest code and follow the manual

also if you inspect the code it has this mark

#-win32

So if you are using windows 32 bits this should not work
