There is a powerpc64 pool machine available.  I believe it's gcc110.

Couldn't reproduce on x86_64, so I am on gcc110 trying to get a
bootstrap compiler build going to reproduce. Also see the dup with
testcase (again doesn't reproduce on x86_64, so I will try this on
gcc110 as soon as I get the compiler built).

Thanks,
Teresa

Hi Steve!
Can you confirm whether the patch I just sent also fixes the mips failure?

Thanks,

My mips build seems to be working with the patch.  It has gotten past the point
where it died last night but the complete bootstrap isn't finished yet.
