gcc 3.2.3 / IA-32 optimization bug w/ 64 bit parameters

["Luedde, Mirko" <mirko dot luedde at sap dot com>]

Hi, 

below's the command line and output. 
Attached is the `.ii' file and my original source file including comments.
Access to 64 bit values on the stack is completely off.

Thanks, Mirko. (Didn't understand how to use Bugzilla).
