Astropulse gets a segmentation violation consistently.
Ubuntu 10.04, Intel Core Duo. Nvidia N9500GT.
glibc 2.11.1
Suggestions on how to either avoid the segv
or avoid astropulse?

Avoid Astropulse? Your Computer -> Seti@Home preferences -> Edit -> check only Seti@Home Enhanced, uncheck "If no work for selected applications is available, accept work from other applications?" -> Save changes to the web site.

At the next time your BOINC contacts Seti, it'll use those preferences.

As for "process got signal 11", see this FAQ.

Thanks. I just realized (looking at task pages on Seti website) that while
Astropulse almost always segv's it has completed on
a couple of occasions (credit pending verification).

Changed preferences to avoid astropulse. Again, thanks for the tip.

Just FYI, 14 astropulse tasks got Signal 11, 2 completed
and are pending verification.

ap_client_version 6.10.17
Many had Signal 11 failures after 10+ chunks (mainloop()), a few
failed on the first chunk.

Could be it's just something that doesn't like your computer or Linux distro's kernel version. But difficult to trace, as are all segvaults.

Yup. Been tracing Unix segfaults since ~1980 and some of them have been
very very difficult to understand. Some of them my own fault :-)
