[PATCH] Fix possible buffer overflow bug in x86_64-tdep.c

[Mark Kettenis <kettenis@chello.nl>]

The attached fixes a possible buffer overflow in
x86_64_store_return_value().

(Andreas, this was the bug I mentioned to you yesterday).

Andreas forgot to check in his origional patch on the 6.0 release
branch.  I'll do so shortly with this fix included.

Checked in.
