Hello all,
Running mprime 23.9.2 on my i686 Linux 2.44.22 (Fedora Core 1), I get a segfault after "stage 1 GCD" :
I experience the same problem running Fedora Core 3
Could someone try this on version 24.6. I did find one rare memory corruption
bug in the GCD code.
See http://www.mersenneforum.org/showthread.php?t=3387
for a discussion of version 24.6. It is faster on Athlons, slower on P3s,
no change on P4s. So far no major bugs reported.

George,
I have been running mprime-24.6 on my Fedora Core 3 system since it was posted at http://www.mersenne.org/gimps/ without any problems.
Tom
