Work unit calculation fails with SIGILL

[Christian Lins]

Using boinc and boinc-app-seti from the repositories on my Toshiba AC100 (armhf architecture) the calculation of WUs fails with the following error message:

<core_client_version>7.0.27</core_client_version>

I'm building boinc 7.0.53 and boinc-app-seti in my ppa right now, in the meanwhile could you try only boinc-app-seti from my ppa [1]?

I just need to know if the problem is only in boinc-app-seti or in boinc too

thanks

In a few hours boinc app seti will be available in my ppa [1] too.
(less frequen updates than the previous one)

I tried boinc-app-seti from your PPA without luck. At first together with boinc from main repositories, then your boinc version.
In both cases I got calculation errors, see http://setiathome.berkeley.edu/result.php?resultid=2848721919

Is it possible that this is not a bug of boinc-* but of g++? Perhaps g++ is generating a invalid opcode or is using ARM extensions the Tegra2 does not support?

[Gianfranco Costamagna (costamagnagianfranco)]

I'm packaging right now a new release, please try again in a few hours

Same error...

[Gianfranco Costamagna (costamagnagianfranco)]

Hi Christian, could you please explain which seti version are you running on? does this ahppens with the official seti client too? a new seti release has been uploaded on debian today, and will be available in saucy soon.

Would be also nice if you can provide a stacktrace with boinc-app-seti-dbg.
thanks
