Description Chris McCormick

There is a test case, regresstest/src/rovtests/InstanceTest1 which was failing because it set Defaults.common$.fxntab = false; but was dynamically creating some instances. Dynamic instance creation references the instance heap abstractly and needs the function table to be present.

InstanceTest1.cfg contains a line HeapMin.common$.fxntab = true; to get it working. Removing this line should reproduce the issue.

A couple points:
1. We may be able to avoid this issue by knowing whether function tables are needed for a particular module and setting fxntab = true behind the scenes.

2. If the function table is not present, it'd be nice if this resulted in a build or runtime error rather than executing bad memory.
