Subject: [Bug libstdc++/23528] New: Wrong default allocator in ext/hash_map

The attached testcase compiles and runs correctly with gcc 3.3.4, but gives the
following compilation errors with gcc 3.4.4:

hashtest.cxx: In function `int main()':
hashtest.cxx:11: error: cannot convert `int*' to `std::pair<const int, int>*' in
initialization
hashtest.cxx:12: error: no matching function for call to
`std::allocator<int>::construct(std::pair<const int, int>*&, std::pair<const
int, int>&)'
/usr/lib/gcc/i386-redhat-linux/3.4.4/../../../../include/c++/3.4.4/ext/new_allocator.h:96:
note: candidates are: void __gnu_cxx::new_allocator<_Tp>::construct(_Tp*, const
_Tp&) [with _Tp = int]
hashtest.cxx:17: error: no matching function for call to

hashtest.cxx:18: error: no matching function for call to

/usr/lib/gcc/i386-redhat-linux/3.4.4/../../../../include/c++/3.4.4/ext/new_allocator.h:86:
note: candidates are: void __gnu_cxx::new_allocator<_Tp>::deallocate(_Tp*,
size_t) [with _Tp = int]

The reason for the errors are wrong default allocators in ext/hash_map. A patch
that fixes the problem is attached.
