We found more bugs in the code, and here is an updated patch to fix them.
Note this patch supercedes the one I sent yesterday.

Also attached is the test program we used to verify the fix.

I'm not able to reproduce the bug with your test case ...

Hi,
I opened a bug with RedHat about a problem with strncpy() in glibc-2.2.4-30 on IA64, see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76952, but I've been told you folks are really the ones to talk to.
 
The bug report contains a testcase illustrating the problem, and also a patch.  In short, the recovery code is busted, even after the patch from David Mosberger.  Attached is a copy of the patch from the bug report.
 
I have a testcase which exercizes both the recovery3 and recovery4 paths if you're interested.  
Regards,
-reese faucette
