Thanks, Wenji. I already knew I'd fixed the bug. ;-)
The bug in question only ever affected a 32-bit process on a 64-bit kernel.
That test as written hits the assert when built for x86_64. Changes to %cs
or %ss have no effect on a 64-bit process, so the traced process does not
crash as a 32-bit

That is not true, unless I am misunderstanding what you are referring to

Thanks for the test, http://sourceware.o

Hi,
The x86_64-cs in utrace wiki page reports that the test could crash
kernel. I verify that in old kernel release 2.6.24.
But in latest kernel 2.6.25-rc1, the problem seems to be resolved.
The call tree :
arch_ptrace -> putreg-> set_segment_reg
In function set_segment_reg, the relat
