The bug was probably in the glibc interface to the kernel. Google found
this:

http://sourceware.org/ml/libc-hacker/2004-03/msg00000.html

i.e. posix_fadvise appears to have been broken on all 64-bit
architechtures prior to March 2004 due to a silly linking error.

And then things like this:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=313219

Which suggest that prior to glibc 2.3.5, posix_fadvise crashed on 2.4
kernels. That's a fairly recent version, so the bug would still be
fairly widespead.

Have a nice day,
