I can confirm the problem on windows. Using a greater range of notes produces
some "interesting" output...

Subject: Re: staffSize music function unreliable at LP v2.19.16
No problem on my side (see attached).
OS : Ubuntu 14.10
Frescobaldi 2.13
LP 2.19.16
Here's a compilable code:
\version "2.19.16"
staffSize = #(define-music-function (parser location new-size)
(number?)
#{
\set fontSize = #new-size
\override StaffSymbol.staff-space = #(magstep new-size)
\override StaffSymbol.thickness = #(magstep new-size)
#})
Ab = \relative c' { f4 g a b }
\score {
\new Staff \with { \staffSize #2 } { \Ab }
\layout { }
}
Cheers,
Pierre

produces at LP v2.19.15:
but at LP v2.19.16 produces:
Besides being wrong (see, e.g., "Behind Bars" by Elaine Gould, p.13),
this causes many scores to require an additional page.
Applying convert-ly to the above snippet changes only the \version number.
I tried all values for new-size between -8 and +8; the only ones that
failed were -4 and 2.
(The staffSize music-function was kindly contributed by Eluze in 2013 on
this list to overcome limitations of layout-set-staff-size.)
I have been able to reproduce the problem on Windows 7 with Frescobaldi
2.17.2.
Additionally I found that sizes of 2.1, 1.4, 1.1, 0.7, 0.5, -0.2, -0.3,
-0.6, -1.3, -1.4, -2.1 also created the down stem on the F. (I only tested 2.1
to -2.1).
