[Bug c++/33581] New: OpenMP segmentation fault

[spollmann at gmail dot com]

The following code (a general case) generates a segmentation fault when
compiled with the -m32 and -fopenmp switch in gcc 4.2.1.  With the -m32 switch
removed, the program executes correctly.

#include <iostream>

int main()
{
  int x;

#pragma omp parallel for
  for (x = 0; x < 100; x++)
    {
      std::cout << x << std::endl;
    }
  return 0;
}

compile command line: /usr/local/gcc-4.2.1/bin/g++ --static -fopenmp -m32 -o
openMPTestProgram openMPTest.cpp

System:  SUSE 10 x64 linux distribution, 
(Dual-core Intel(R) Pentium(R) D CPU 2.80GHz system), 4GB ram

GCC configuration option: ../gcc-4.2.1/configure --prefix=/usr/local/gcc-4.2.1
