Ok, that is also a result. I'll keep investigating.
Two thoughts though:
I use a newer icc:
"Intel(R) C Itanium(R) Compiler for Itanium(R)-based applications
Version 8.1    Build 20041123 Package ID: l_cc_pc_8.1.026
Copyright (C) 1985-2004 Intel Corporation.  All rights reserved."

I don't remember if that also means that libipr got updated (Intel 
release notes doesn't reveal info about the libraries and they don't 
contain any usable version numbers :-(. My libraries have the following 
checksums:

address@hidden:~/src/NIL$ sum --version
sum (coreutils) 5.2.1
address@hidden sum /opt/intel_cc_80/lib/libipr.*
07346    12 /opt/intel_cc_80/lib/libipr.a
00999     1 /opt/intel_cc_80/lib/libipr.so
32283    13 /opt/intel_cc_80/lib/libipr.so.6

Secondly, since name resolution in dynamic libraries isn't the most 
predictable activity that I know: Can you verify that your build/run 
results in Intel's personality routine calling your _ReadSLEB?
