Couldn't you just add a Boolean variable to your calling sequence that you
set to TRUE if you call the procedure from an exception handler and FALSE if
you call it from normal flow.  Or else use an enumeration variable that is
set to either EXCEPTION or NORMAL:

--------------------------------------------------
Procedure Foo(...) is

Type Calling_Source_Type is (Exception, Normal);

Calling_Source : Calling_Source_Type

.
.
Calling_Source := Normal;
Handler (Calling_Source);

Exception:

Calling_Source := Exception;
Handler (Calling_Source);
--------------------------------------------------

Procedure Handler (From_Where : Calling_Source_Type) is
.
.
if From_Where = Exception then
.
..
End IF;

--------------------------------------------------
