Default Where is /usr/lib/libc/memcpy-preload.so ?

Hi,
In*/usr/share/doc/libc6/NEWS.Debian.gz it reads:
eglibc (2.13-3) unstable; urgency=low...* For this reason, on the amd64 architecture the Debian package provides*

* two wrappers which can be use to workaround and/or debug the issue:* - /usr/lib/libc/memcpy-preload.so simply replace all calls to memcpy()* * by a call to memmove()* - /usr/lib/libc/memcpy-syslog-preload.so does the same, but in addition*

* * logs (with rate limit) the issue to syslog, so that it can be** * detected and fixed.
But in which package can I find*/usr/lib/libc/memcpy-preload.so ?I have libc6 2.13-6 installed, but that file is just missing.


Thanks & best regards,Wang Long

It has been moved to the multiarch path,
/usr/lib/x86_64-linux-gnu/libc/. The NEWS.Debian file needs to be
updated to reflect that.

Note that the wrappers only exist on amd64.

Cheers,
Sven
