  Getting ORA-07445: exception encountered: core dump [spefm_fixup_list()+146] [SIGSEGV] [ADDR:0x180] [PC:0x33C6CCE] [Address not mapped to object] []

after db clone completed and target db started . Investigation points to *_segments views causing the errors specifically querying sys_dba_segs;

select decode(bitand(segment_flags, 131072), 131072, blocks, (select decode(bitand(segment_flags,1),1, dbms_space_admin.segment_number_blocks(tablespace_id, relative_fno, header_block, segment_type_id, buffer_pool_id, segment_flags, segment_objd, blocks), blocks)))

from sys.sys_dba_segs;

Select * from sys_dba_segs returns data ok  no negatives numeric values.

Seems like dbms_space_admin.segment_number_blocks is thowing ORA-07445 and crashing user sessions.

Howdy, Stranger!
