Wait - lseek returns a number less than -1?! We could easily check for
that FreeBSD bug, perhaps as an independent patch; this shouldn't
require any extra syscalls.
I installed the attached patch to do this. This doesn't fix coreutils
bug#51433; it merely makes 'cp' and similar programs more likely to
detect and report the FreeBSD 9.1 bug you mentioned.
On further inspection it seems the bug is in truss :/
I.e. the only bug on FreeBSD 9.1 is that the SEEK_DATA takes ages,
but the returned values are correct.
I.e. SEEK_DATA was returning 1099511595008 in this case
which truss was reporting in 32 bit rather than 64 bit.
I see other inconsistencies in truss output,
so it can only be relied on for what syscall was called,
rather than what was passed/returned.
Given this patch doesn't change any operation,
it may be best to revert to avoid the complexity?
