I have no idea.

Disabling on MIPS made it fail on ARM. Disabling on ARM made it fail
on PowerPC. I say this test is busted.

This looks like one of those tests that are more dependent on the
environment (libc version, etc) than the architecture, so I'm not
hopeful it will every be stable on the number of different bots we
have.

Evgeniy, any idea why it fails randomly on all arches? Is this an
x86-only kind of test? Or requires a specific version of glibc?

cheers,
