yes, uname says 2.6.14.2; on a second identical machine, I've just seen this:
factorial[2352]: segfault at 0000000000020f31 rip 00000000004035ae rsp 00007fffffbfaf60 error 4 factorial[2354]: segfault at 0000000000020f31 rip 00000000004035ae rsp 00007fffffe3fc70 error 4 factorial[2361]: segfault at 0000000000020f31 rip 00000000004035ae rsp 00007fffffb07c50 error 4 factorial[2358]: segfault at 0000000000020f31 rip 00000000004035ae rsp 00007fffffb07c50 error 4 factorial[2363]: segfault at 0000000000020f31 rip 00000000004035ae rsp 00007fffffe6d270 error 4 the kernel and HW are the same.
