 Hello,
 
 I can confirm that this bug occurs on gcc 3.2.3, but on gcc 3.3 branch  
 and mainline (20030509) I get no ICE in the testcase with -O3 -msse.  
 Would it be possible for the submitter of this bug to verify whether  
 the bug still exists for them?

 Hello,
 
 well judging as how this can't be reproduced on either active gcc  
 branch (3.2 is now closed), I'd vote to close this bug, but if you have  
 a reason to keep it open, feel free to say so.

 I'm sorry, but I don't have a spare system to play with newer gcc 
 versions. I know this is not what you expect from a bug reporter (I 
 won't, too).

    Confirmed. Here's a much reduced testcase:

      if (*outSI)
        *outSI = trueValue;
