If you mean that the order (in which LilyPond determines the sizes and 
locations of things) changes from run-to-run, I do not think that is a 
problem.

For purposes of regression testing, `make check` creates .signature files
that have the sizes and locations of every object LilyPond draws.

It is true that, if you look at two corresponding .signature files 

  out-test-baseline/accidental-placement-1.signature
  out-test/accidental-placement-1.signature

they will usually differ.

But, if you sort them, they come out the same.  If the sorted versions come
out the same, the regression tester reports no difference.
