This is the backtrace of x264. I just decided to run one of the

Previous frame inner to this frame (corrupt stack?)
I get the same backtrace with or without input data to the test
program.

Slightly de-railing this topic, we probably should add a parsec
benchmark to the regression suite. It would catch some errors that we
might not otherwise see in terms of FS mp.
What are the segfaults. Can you run in GDB and give us a backtrace?

Well it happens regardless of if i use m5-stable or this changeset.
Do you recommend a different version thats more up to date that
m5-stable that should work?

That's the architecture affected by the most recent change, but not
necessarily the architecture being used. Is the simulator itself
segfaulting, or is it a simulated segfault? The first shouldn't
happen
under any normal circumstances, so if it is we need to fix that.

Quoting ef <[email protected]>:
Parsec doesn't run in SE mode at the moment, and its probably not
worth it
to make it do so.
The parsec images are compiled for ALPHA, it looks like you are
running x86.

I've also tried running the image provided by this group at UTexas

Has anyone managed to run the benchmarks off this image. When I try
to
execute the benchmarks they all quit abruptly with a segmentation
fault.
My current changeset is:
changeset: 7715:5581d0cd2bdb
tag: tip
user: Gabe Black <[email protected]>
date: Fri Oct 22 00:24:15 2010 -0700
summary: X86: Make nop a regular, non-microcoded instruction.
Please let me know if you've managed to get this to work or have
some
suggestions on what to look at to fix it
Thanks,
