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
