Angry Segmentation Fault

I've run 7 prime number tests smoothly and then ran into problems with this assigned number. I get the error shown below. I've tried varying allocated memory from 32 to 256 MB, tried two fresh Fedora 2 installs, kernels 2.6 and 2.8. Nothing else is running on my 2.8 GHz Pentium with 512 MB RAM besides mprime. Also ran a day of torture tests.

Does anyone have any suggestions of what I can else I can try to get around the segmentation fault? I don't think I am able to do any recompilation of mprime.

Thank you for your help. I'd hate to abandon GIMPS because of this bug--it's been fun.

Try the latest version: ftp://mersenne.org/gimps/mprime239.tar.gz

Should work better with the latest Fedora 2 kernels.

Change your worktodo.ini file so that it says:

Test=25855931,68,1

If you can, email the current P-1 save file to me.
