This is as far as I got toward a tiny example:

\paper {ragged-right = ##t }
\relative f {
    \key a \major
    s1 \break
    r8 a'''8^( gis fis
    gis fis e)-1-4-5 r

The 2.15.12 build for Windows puts 1 4 and 5 all on top of each other.

The problem is associated with "no solution found for Bezier intersection"
so it frustratingly goes away when the slur changes shape slightly.

Note that 2.15.12 is after Joe's commit 
"Cleanups and generalizations in Bezier::minmax."
