This is not a GCC bug (<http://gcc.gnu.org/PR46863>), but it is a glibc
header bug (<http://bugs.debian.org/619963>).

After fixing the bits/string3.h header of my 2.11.2-13 glibc package
according to
<http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=42acbb92c861e97a6e1293ea853db88342a1bf53>,
the error is gone.  This fix should already be in the Debian 2.13
packages.


We need to tell <address@hidden> about these findings; is this
correct?

reassign 619963 eglibc
reassign 624743 eglibc
forcemerge 619963 624743


Grüße,
 Thomas
