             Bug #: 51540
           Summary: partial_sum (int *, int *, int *, multiplies < int >)
                    does not use operator +(complex, complex)
    Classification: Unclassified
           Product: gcc
           Version: 4.5.1
               URL: http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen
                    /a01567.html#a17bad49fa9fb1c5c41d019b16970fe9e
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: giecrilj@stegny.2a.pl
              Host: i586-suse-linux
            Target: i586-suse-linux
             Build: i586-suse-linux


The following code fails to run:

int main () 
{ 
  int x [02] = { 0, 01 }; 
::std ::partial_sum (x, x + 02, x, ::std ::multiplies < int > ()); 
assert (+x [01] == 01); 
 return +EXIT_SUCCESS; }

Actual result: 
int main(): Assertion `+x [01] == 01' failed.

Expected result: 
I do not know, 
as the documentation does not say which complex class should be used.
Maybe it should not compile at all.
