 You know, I was hoping you would say that :-)

oh .. that explains why I see no error there :-(

OKay ... that would be this guy :

bash-3.2$ pwd
/opt/build/gcc-4.2.1-build

bash-3.2$ prev-gcc/xgcc -v

Now that is excellent thinking.

Let me have a whirl at it :

bash-3.2$ cat /tmp/hello.c
#include <stdio.h>

int
main(int argc, char *argv[])
{
    printf ( "Hello World!\n" );
    return (0);
}

I ran this for just the preprocessed compile stage first :

http://www.blastwave.org/dclarke/gcc-4.2.1/gcc-4.2.1-stage1-test.txt

Then I generate the assembly :

http://www.blastwave.org/dclarke/gcc-4.2.1/gcc-4.2.1-stage1-assembly.txt

And *that* also looks very good.

This does not look too good :

http://www.blastwave.org/dclarke/gcc-4.2.1/gcc-4.2.1-stage1-hello.txt

okay .. so that reveals some info.  I think.
