unrecognized attribute code: 55

[Albert Öttl]

During porting an application from AXP to IA64
I encountered the following stackdump.
The reason for the dump is obvious, there was
an array index out of range (it was zero) in routine UTIL$TRIM
and the error has already been fixed.

What I am curious of is the repeated line
"unrecognized attribute code: 55"
I didn't find anything in the documentation about
this specific error code.

Does anyone know what this means?
Thanks in advance for your help.



%PAS-F-ARRINDVAL, array index value is out of range
%TRACE-F-TRACEBACK, symbolic stack dump follows
image module routine line rel PC abs PC

I wonder if the code that displays the stack traceback is finding something on the stack it does not recognise?

One to reported to hp I think.

Albert,

Interesting! I suspect it's something in the TRACE code that's getting confused when symbolizing the call stack. Note it's just for stuff in LSS$LSS. How was it linked?
