System: NetBSD sunny-weather.duskware.de 2.99.12 NetBSD 2.99.12 (SUNNY) #2: Mon Jan 3 12:55:16 CET 2005 martin@sunny-weather.duskware.de:/usr/src/sys/arch/sparc64/compile/SUNNY sparc64
Architecture: sparc64
Machine: sparc64
>Description:

In some cases building a kernel (natively) on sparc64 fails because
"newvers.sh" generates broken C code in vers.c. This bug is not new, it
has been triggered by addition of 2005 to the copyright message.

>How-To-Repeat:
This looks like a memory management bug in /bin/sh. It is highly volatile:
copying "copyright" and "newvers.sh" to /tmp and running it there fixes the
bug. Removing the "5" from "2005" in "copyright" avoids it too.

Of course (heh!) everything works fine on 32bit archs.

Here is a sh -x transscript showing the bug (note the missing " after
the second "All rights reserved.")

The awk output itself is ok:
