Overview
========
The following code fails to compile on ia64 platform with standard options. The
problem is gone when:
- removing the #pragma or
- declaring a double instead of a vector or
- not explicitly assigning a length to the vector
- inlining foo()
Problematic code:
=================
#include <vector>
#include <omp.h>
class A {
void foo();
};
void A::foo() {
#pragma omp parallel
{
std::vector<double> x(0);
}
}
Steps to reproduce
====================
Compile using
g++ -Wall -fopenmp -save-temps -o ice.o -c ice.h
Build Date & Platform
=====================

GCC version: SVN revision 131821 (2008-01-25) (I don't know about earlier or
later versions)
GCC was configured with

The bug does not show up on amd64 using the same revision.
