Is this ICE also comes from compiling the codes that you attach in this PR?
If yes, I am pretty sure this issue has been fixed since I compile the
attachment you gave with no fails now.

Let's wait for kito to merge all the bug fix patches (there are about 5 bug=
 fix
patches pending in the GCC mail list)

Thanks.=
