INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

Should compression dictionary partitions contain old
dictionaries for partnums whose partition header pages now serve
as secondary partition header pages (describing in-place
alters), purging such dictionaries using
sysadmin:task("compression purge_dictionary") would throw an
assertion like the following for every such dict_partnum in
sysmaster:syscompdicts:

  Assert Warning: pthdrpage:ptalloc:bad partn page

These really are warnings only and would neither pose nor create
any problem.
