In my experience, the best first step is to fix the compiler
warnings.  This often fixes the problem without having to
hunt for it.  (And is a good idea anyway.)

If that doesn't work, then it's time to gather some data.
(fire up a debugger, add/turn-on print statements, ktrace, ...)

   -Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes
   -Wpointer-arith -Wimplicit -Wreturn-type -Wformat

I always fix the decl/prototype warnings first, and then recompile
to get a fresh set of warning messages.  Otherwise the other warning
messages can be incorrect.
