I have using vfork reliably. This fails every time on my PA8700 system
running 2.6.32-rc6. It appears as though r28 (ret0) in the parent is
being corrupted.
The test doesn't fail on two of my builds:
Linux mx3210 2.6.31.7 #5 Wed Dec 9 22:49:53 EST 2009 parisc64
Linux hiauly6 2.6.31.7 #18 Wed Dec 9 21:34:36 EST 2009 parisc
I did tested your testcase on my c3000 too but it didn't failed for me either.
This was on some 2.6.32-rc candidate.
I think it must be because Carlos is building SMP kernels.
I couldn't reproduce on my SMP box either (but it's PA8500 instead of PA8700):
cpu : PA8500 (PCX-W)
model : 9000/785/J5000
Linux ls3017 2.6.32-32bit #79 SMP Thu Dec 3 14:04:53 CET 2009 parisc GNU/Linux
