The ICE goes away when compiling without -O2.

What exact version of 3.4.4 is this aka give the output of "gcc34 -v".

Also if this is a three week old snapshot, try a newer snapshot as I think this has been fixed already.

Ignore the "gcc -v" that claims to be 2.95.4.  That's from the wrong gcc.

Here's the right info:

I think this is a dup of bug 18932 which is already fixed in a later version of 3.4.4, can you try a newer 
version of 3.4.4?
