-O3 works on my box too

I just tried on solaris9 with gcc 3.4.2 - seems the bug is fixed in this  version. Unfortunably it is quite problematic
tochange the compiler 
 
at least on OpenBSD gcc 3.3.2 is quite heavily modified on that platform 
and switching the base system compiler might screw a boatload of other 
tools.
The actual recommendation I got from the OpenBSD-folks was to add 
"-mfaster-structs" to the compiler flags with seems to work around the 
issue - I'm currently doing a full build to verify that though ...
