In addition to sparse (which finds some of these), I also run a perl
script over the object files after a given build. (The script was
posted to the list by Junio, many moons ago, and I have made several
changes to my local copy).

I am attaching a copy of the script (static-check.pl). Note that the
'stop list' in the script (%def_ok) is _way_ out of date. However, the
way I use the script, that does not matter; I run the script over the
master->next->pu branches and (ignoring the master branch) diff the
result files from branch to branch. For example, tonight I have:

  $ wc -l sc nsc psc
    74 sc
    73 nsc
    75 psc
   222 total
  $ 
  $ diff sc nsc
  44d43
  < oidmap.o	- oidmap_remove
  $ 
  $ diff nsc psc
  43a44
  > list-objects-filter-options.o	- partial_clone_get_default_filter_spec
  58a60
  > sequencer.o	- sign_off_header
  $ 

You also have to be careful with leaving stale object files
laying around from previous builds ('make clean' sometimes
doesn't). Actually, it may be simpler to read a previous mailing
list thread on exactly this subject [1].

BTW, if you are using a version of sparse post v0.5.1, you can
get rid of the only sparse warning on Linux (assuming you don't
build with NO_REGEX set), by using the -Wno-memcpy-max-count option;
I have the following set in my config.mak:

  $ tail -2 config.mak
  pack-revindex.sp: SPARSE_FLAGS += -Wno-memcpy-max-count

  $ 

[I haven't sent a proper patch, since the required version of
sparse is not widely available yet.]

ATB,
