FW: Bug in the vxWorks cross compiler


In the compiler shipped with the vxWorks 5.5.1 we have found a bug when
-O2 is used.  The compiler version is 2.9.6+, the error happens on both
the Solaris host and on a Linux host.  The target is PPC.  Has anyone
seen this in other versions of the compiler or know what the fix is?

#include <stdio.h>


int test(int argc,char * argv[])
{

    double stack[]={0.0,1.0};
    double * pStack=&stack[0];
    double response;

    response=(*pStack==*(pStack+1));
    printf("Response=%f\n",response);
    return 0;
}

Response gets set to 1 instead of the expected 0.
