I get the following ICE with gcc 4.2 20060508 and 20060530 on mipsel. 
Actually,  I get this with gcc 4.0 and 4.1 too.  gcc 3.4 works.

Are your host and build machine really mipsel-linux-gnu?  Or is this a cross to
mipsel?

... but you can also see it with a x from i386 to mipsel.

------- Comment #10 from roger at eyesopen dot com  2006-06-22 04:46 -------
This should now be fixed on all active branches.  Thanks to Martin for
confirming the fix bootstraps and regression tests fine on mipsel-linux-gnu.
And thanks, as always, to Andrew Pinski for maintaining the PR in bugzilla.
