[svn-r2583] Purpose:
    Bug Fix.
Description:
    An assertion in the local heap code was mistakenly checking against too
    large of a value for the size of new local heap created.  When used with
    larger-sized (>10KB) variable-length objects, it was failing the check.
Solution:
    Corrected to check against the actual size of the heap allocated, without
    the heap header.
Platforms tested:
    FreeBSD 4.1
