There are various known deficiencies with the variety of Poly/ML versions
that we support officially -- David Matthews is continously improving the
situation. One needs to try minimizing the pressure on old versions to
keep things running, without forced discontinuation of a version without
really strong reasons.
In Isabelle/344712917580 I have tweaked isatest again, and for the moment
it looks like the failure does not happen in this configuration.
