	Large files are standard Unix, and are being phased in

	on something that the vendors promise to remove!

	Those warnings are the tip-off: we need to hunt down the

	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.

	Please note:
		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?
