bug of handling complex number in ICC when using "-O3 -ip" on IA64

[yager]

testcomplex.cpp:

#include
int main()
{
using namespace std;
complex < double > c(1,2);
double d[2];
d[0] = c.real();
d[1] = c.imag();
return 0;
}

Compile it,

icc -V -O3 -tpp2 -ip testcomplex.cpp
Intel C Itanium Compiler for Itanium-based applications

compilation aborted for testcomplex.cpp (code 4)

But old ICC works fine,

/opt/intel_cc_80/bin/icc -V -O3 -tpp2 -ip testcomplex.cpp
Intel C Itanium Compiler for Itanium-based applications

GNU ld version 2.15.92.0.2 20040927
Supported emulations:

==============================================

Now add the following at the beginning,

#include < vector >
#include < iostream >

and the following before "return 0;",

vector < complex < double > > vc;
vc.resize(5);
double vd[10];
for (int i=0; i<5; i++) vc = sqrt(complex < double > (-i));
for (int i=0; i<5; i++) vd[i*2] = vc.real();
for (int i=0; i<5; i++) vd[i*2+1] = vc.imag();
for (int i=0; i<10; i++) cout << vd << " ";
cout << endl;

Then both versions refuse to work,
