Yes, it's definitely a bug in the new symbol table code.

The situation is not quite this bad.  First, the problem is a bug that
only appears in the main development trunk of the CVS sources, and
will be fixed before 3.1 is released.  The 3.0 branch in CVS (the one
from which any 3.0.x releases will be made) only contains bug fixes.
We are not merging big changes like the new symbol table code on that
branch.  So I think it is safe for you to keep the >= 3.0.0
dependency.
