It worked (patch applied on top of 3.2.1). Thanks. Now I have the next 
one... :-\

I have switched from ICC to GCC, but I still use IPP-compiled code (IPP: 
Intel Performance Primitives) which seem to use some other new 
instructions. My box is still Pentium4/Prescott, running FC3 with 
32-bits kernel & HT turned on (in case that matters).

==27913== Your program just tried to execute an instruction that Valgrind
==27913== did not recognise.  There are two possible reasons for this.
==27913== 1. Your program has a bug and erroneously jumped to a non-code
==27913==    location.  If you are running Memcheck and you just saw a
==27913==    warning about a bad jump, it's probably your program's fault.
==27913== 2. The instruction is legitimate but Valgrind doesn't handle it,
==27913==    i.e. it's Valgrind's fault.  If you think this is the case or
==27913==    you are not sure, please let us know.
==27913== Either way, Valgrind will now raise a SIGILL signal which will
==27913== probably kill your program.

Do you want me to fill a separated bug-report in 
<http://bugs.kde.org/enter_valgrind_bug.cgi>?

Thanks.
