Step 0: try the current official release Isabelle2016-1 (December 2016).
Historic Isabelle versions should not be used anymore, unless there are
special reasons for that.

Step 1: You can try the 64bit version of Isabelle/ML, by enabling the
option ML_system_64, e.g. in Isabelle/jEdit "Plugins / Plugin Options /
Isabelle / General / ML System 64". Then restart / rebuild the
application. In 64bit mode the only limit are available system
resources, so instead of a Size exception (e.g. for strings and other
blobs > 64 MB) there might be a total existence failure of the ML
process without exception :-) :-(
