 Thanks for your experiments. I think there is no need for you to try an 
 even newer snapshot. The only thing you could do is try to strip down the 
 testcase as much as possible, presently it is rather long. We usually do 
 that by first stripping off the line number lines using
   perl -pi -e 's/^#.*\n//g;' expr.i
 so that the compiler gives the _actual_ line number in this file when it 
 crashes. Then try to delete as much stuff from the file as you can. 
 Usually, one can get it down to 20-30 lines and still see the crash. But 
 be warned that this can be a tediuous process that could take 30 minutes 
 to an hour, if you're not frequently doing such things.
 
 Thanks for your help
   Wolfgang
