>Environment:
fstat from NetBSD-6.99.14/i386
kernel from netBSD-6.99.14/amd64
>Description:
	An i386 fstat(1) fails on am amd64 kernel, with messages like this:

fstat: can't read filedesc at 0x18c0c1c0 for pid 2553
fstat: can't read filedesc at 0xf8f5440 for pid 2321
fstat: can't read filedesc at 0x1beba740 for pid 3090

	The same failure would probably also occur with other
	pairs of machines, such as sparc userland on sparc64 kernel.
