Are you sure the above is a ppc64 executable and not a ppc32 executable ?

If that is a ppc32, the problem above might be due to a bug in Valgrind 3.7.0 ppc32 :
some xml files were missing in the install. So, GDB does not get the register description
for the Valgrind ppc32 simulated CPU. This might then cause the above 'packet too long'.
Testing in 64 bits and/or testing with the (not yet released) Valgrind 3.8.0 SVN should
be ok then. 

If this is not the explanation, then some more info might help to understand
what goes wrong (e.g. full log of Valgrind -v -v -v -d -d -d when doing the above test).


Thanks

Philippe
