[Soot-list] I got a heap memory error

[Eric Bodden]

Hmm, indeed there appears to be an infinite loop in the worklist
algorithm of the type assigner.

Does this also happen when you do not use the phantom-refs option? The
use of phantom refs applies some tweaks to the type assigner, not all
of which may be correct.
