Bug#478734: g++-4.2: refuses to compile valid C++ syntax

[Jason Kraftcheck <kraftche@cae.wisc.edu>]

Package: g++-4.2
Version: 4.2.3-4
Severity: grave
Justification: renders package unusable


g++ refuses to compile the following syntax commonly used to force a 
std::vector to release allocated memory:

  #include <vector>
  int main()
  {
    std::vector<int> v;
    v.clear();
    v.swap( std::vector<int>(v) );
    return 0;
  }

I emmits the following  error message:

bug.cc: In function 'int main()':
bug.cc:6: error: no matching function for call to 'std::vector<int, 
  std::allocator<int> >::swap(std::vector<int, std::allocator<int> >)'
/usr/include/c++/4.2/bits/stl_vector.h:728: note: candidates are: void 
  std::vector<_Tp, _Alloc>::swap(std::vector<_Tp, _Alloc>&) [with _Tp = 
  int, _Alloc = std::allocator<int>]
