Tested using valgrind 3.6.1 installed via aptitude on Ubuntu 11.04 with default package sources.  Also tested using 3.8 SVN built from source. Getting the following message:

$ valgrind ./progname
...

$ valgrind --version
valgrind-3.8.0.SVN

$ cat /proc/version
Linux version 2.6.38-12-generic (buildd@crested) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4) ) #51-Ubuntu SMP Wed Sep 28 14:27:32 UTC 2011

Not sure if it's useful info, but I am on a lenovo laptop with Intel Core i7-2720QM process and 8GB RAM (cat /proc/cpuinfo attached).

Forgot to mention, this is a Qt application, built using Qt 4.7.3.  Again, not sure if this info is useful, but there it is...
