Is it possible that David is working on a system with exec-shield and
memory layout randomization? In the past when I've seen PCH stuff
randomly pass/fail it's always been solved by turning off the exec-shield
and related bits.

It is a cross compiler running of Fedora 1. This may have exec-shield, I am not sure.

It does and very likely is causing the problems given:

Target is plain Linux 2.4.25-pre6 from w/ glibc 2.2.5 running on a MIPS 4Kc core. But this is not important because the tests that fail are all run on the compiler host.

I have the following in /etc/sysctl.conf

# Turning off exec shield.
kernel.exec-shield = 0
kernel.exec-shield-randomize = 0

If you turn off exec shield and rerun the tests an they pass go ahead
and commit. Otherwise I'd appreciate you looking into it.



Disabling exec-shield cures the PCH failures.

There were no new regressions.

Committed on both 3.4.0 and Mainline.
