[svn-r19544] Purpose:
Patch for metadata accumulator bug
Description:
Linew failed one of the randomly seeded fheap tests
due to a corner case bug in the metadata accumulator code.
This patch fixes the corner case.
Tested:
used same random seed in fheap tests to reproduce and
verify on linew; plus full make check on jam.
unit tests for accumulator code coming soon.
