I have seen this with other containers, including "vector".
It appears to be a problem with an explicit class specialization for
complex<double> (and other types). We reported this to Microsoft a long time
ago, but have not even received an acknowledgement. I can't be sure if it is
a compiler problem or a library problem, though I am suspicious of the
compiler since the template parameter "_Ty" is used at two levels (complex
and container). Perhaps someone here could comment if the standard says
anything about the possible reuse of template parameter names.

In at least one case, we got it to work by commenting out the class
specializations in <complex>.

Good luck.

You need to update your header files, especially <xmemory> from Dinkumware:

They have done a great job in fixing errors in VC header files.

You're hitting a compiler bug that causes problems in template function
_Destroy in <xmemory>. For a workaround, see:

Buggy compiler.

Why does MS Visual C++ 5.0 choke on this (seemingly) simple STL
example?

---snip---
#include <deque>
#include <complex>

using namespace std;

typedef complex<double> CPD;
typedef deque<CPD> DCPD;

int main()
{
   DCPD foo;
   return 0;
}
-------

A deque is supposed to work if the template parameter has a default
ctor,
dtor, and assignment/copy.  The <complex> documentation says it does
but the
compiler reports:

C:\Program Files\major\DevStudio\VC\Include\xmemory(33) : error C2300:
'std::complex<double>' : class does not have a destructor called
'~_Ty'

Any ideas?  Thanks in advance.
