I have tried this again and in 9.2.0.7 it sets BIND_MISMATCH to Y. I will try to find the case I saw to see if I am remembering something wrong.

problems with formatting...resending again...

well, I have a different experience - at least at 10.2.0.2/Linux...bind variable length do count in v$sql_shared_cursor...

GB_at_xxxxxx > var b varchar2(100);
GB_at_xxxxxx > select /* goran2 */ count(9) from brisi where instanceid# =
:b;

COUNT(9)

GB_at_xxxxxx > var b varchar2(200);

GB_at_xxxxxx > select /* goran2 */ count(9) from brisi where instanceid# =
:b;

COUNT(9)

GB_at_xxxxxx > select sql_text, version_count, sql_id   2 from v$sqlarea
  3 where sql_text like '%goran2%'
  4 ;

SQL_TEXT                       VERSION_COUNT SQL_ID
------------------------------ ------------- -------------
select /* goran2 */ count(9) f             2 dv7phzzypq13t

rom brisi where instanceid# =
:b

select sql_text, version_count 1 ghqmf9yaw3ju6 , sql_id from v$sqlarea where
1=1 and sql_text like '%goran2
%'

GB_at_xxxxxx > select sa.sql_text, sc.bind_mismatch, sc.child_number   2 from v$sql_shared_cursor sc, v$sqlarea sa   3 where sc.sql_id = 'dv7phzzypq13t'
  4 and sc.sql_id = sa.sql_id
  5 ;

SQL_TEXT                       B CHILD_NUMBER
------------------------------ - ------------
select /* goran2 */ count(9) f N            0

rom brisi where instanceid# =
:b

select /* goran2 */ count(9) f Y 1 rom brisi where instanceid# =
:b
