This seems to be fixed already for 4.7.1.  Now the compiler says,

.../libstdc++-v3/include/bits/stl_pair.h:132:45: error: array used as
initializer

when the pair constructor tries to initialize one array from another.

I built gcc from gcc-4_7-branch, svn186417.  I can confirm it does not segfault
on my example.

After a little more investigation it turns out this was fixed by the fix to bug
52743.  So I guess this is actually a dup.
