Hello Werner,
thanks for your reply!
Just to make sure we're on the same page: You don't assume that there is
variability across
different runs of the same LilyPond build on the same machine? (Aka some
kind of "non-deterministic behaviour")
That would be my understanding of "randomness", which I find a bit of a
misleading term here.
FWIW, I can confirm that 100 subsequent runs of `lilypond --eps
input.ly` on my machine
produce exactly bit-identical eps files.
Carl and Werner, could you please:
* patch scm/framework-ps.scm with the attached patch (go to the
directory where framework-ps.scm resides
and run `patch < epsdebug.patch`)
(Does not have to be in the source tree, you can also do a backup of
framework-ps.scm and patch your working installation)
This patch will print the page stencils as pretty-printed scheme code to
stdout, while
normal messages go to stderr.
* run `lilypond --eps input.ly > epsdebug.log`
* send me the resulting log files
Michael

Hello Michael,
sorry for the late reply.
I would like to help debugging the problem. Which exact invocation
do I have to use to replicate the EPS files you sent?
This is due to using `extractpdfmark`, which makes the build add the
options
```
-dfont-ps-resdir=$(top-build-dir)/out-fonts -O TeX-GS
```
However,...
If I do `lilypond --eps input.ly` I get a much bigger EPS file, that
seemingly has the fonts attached as binary data.
... it doesn't matter for the problem at hand: you also get the
differences with normal `lilypond --eps` calls.

When writing a figured bass, you can place the figures above or below
the bass notes, by defining the
@code{BassFigureAlignmentPositioning.direction} property (exclusively
in a @code{Staff} context). Choices are @code{#UP} (or @code{#1}),
@code{#CENTER} (or @code{#0}) and @code{#DOWN} (or @code{#-1}).
This property can be changed as many times as you wish. Use
@code{\\once \\override} if you don't want the override to apply to the
whole score.
