[cfe-dev] CLang Static Analysis -- false positives

[Kent Williams]

I'm using scan-build (aka CLang Static Analysis) to check through ITK
(http://www.itk.org).

There is a common 'single exit from function' pattern used several places:

int
somefunc()
{
  int status = EXIT_SUCCESS;
  // do a bunch of stuff, and if there's a failure
  if(failure)
    {
    status = EXIT_FAILURE;
    }
  return status;
}

I tried making a simple test case to flush out this false positive
error, but I can't seem to trigger it.  Is there some trick to this?
