Words 'materialized view' and mview are used interchangeably in this document.
After installing 220.127.116.11.7 PSU (<Patch 16619892>), fast refresh of certain materialized views errors out. All these refreshes worked without error prior to the application of the 18.104.22.168.7 PSU.
If the fast refresh has been initiated while no change needs to be applied to the mview (e.g. corresponding mview log(s) is (are) empty), then the refresh completes, but the following error is logged in the alert log:
ORA-01741: illegal zero-length identifier
Otherwise, the fast refresh may error out with ORA-600 error like the following during parsing the mview definition query:
ORA-00600 [kkzgajdl_dltgen-0], 
ORA-00600 [kghstack_free1], [kkzgjctx:cta]
ORA-00600 [expecting modified table]
Note, you may also see the above errors while commit is done on the primary table of an on commit materialized view, as the commit triggers fast refresh of the mview.
22.214.171.124.7 PSU (<Patch 16619892>) has been applied.
