1. install iozone3
2. run 'iozone -h' and see a backtrace like above
3. install proposed version
4. running 'iozone -h' should display the extensive command line argument options for iozone.

This is very little potential for regression here as iozone3 does not work at all in jaunty.

The fix for iozone-308 is very simple anyway. There's a potential buffer overflow when the hostname is saved into the string controlling_host_name by gethostname(), using a wrong length for the string. See the attachment.

Thanks Andrea. Based on inspection and testing a package built in my ppa ( with the patch applied, I can confirm this fixes the issue. Attached is a debdiff

Accepted iozone3 into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See for documentation how to enable and use -proposed. Thank you in advance!

Tried the proposed version and this on behaves much better, haven't figured out all the command-line switches but the auto tests show results.
