I have a native application working fine in Ubuntu 10.04 but failing in
Ubuntu 12.04 due to overlapping memory passed to strcpy. Kindly let me
know how I can fix/patch strcpy implementationn.

@elango-go
you may fetch an older glibc and preload it before launching your
affected application.
Alternatively, maybe it should be considered to provide a wrapper script
that preloads old variant off strcpy.
Doko, 18 months is long enough... if the software in question is at all
Thanks Dmitrijis. Can you help me/provide pointers how I can preload an

It appears that this has been reverted by Red Hat to the old behavior:

Is Ubuntu going to provide a regression to the old behavior??

Invalid? First, the application has not fixed it. They don't support
every kernel as it comes out, so I have a choice between running Ubuntu
or running my primary work application.
Second, not everyone (see the link the original report) sees this as a
