In that case, I'd look at the offset calculation that's
being screwed up!

Large files are standard Unix, and are being phased in
by all vendors as we speak: it's a really bad idea to
try to compile them out, as you would be choosing to depend
on something that the vendors promise to remove!

Those warnings are the tip-off: we need to hunt down the
erroneous shifts and repair them.

I can reproduce the segfault on a 64-bit Solaris 8, but
never saw it on my (former) 2.6 or 2.7 machines, or
Solaris 8 compiled in 32-bit mode.
Solaris 2.6 is a 32-bit os with 64-bit filesizes.
Solaris 7 can be run as either a 32 or 64-bit os,
and has 64-bit filesizes in either case.
Solaris 8 ditto.
Sun compilers default to building 32-bit binaries for
any of those Solarii: these include 64-bit filesizes
defined as long longs.
Am I correct in thinking you're compiling with gcc in 32-bit
mode, or are you building a 64-bit samba application?
