Hi, Sorry, I was a little too concise and didn't show the code that checks for fd == 0. In this case fd == 3. > can't open path. You should debug your code.

I think it might be a linking mixup. Now I'm seeing a negative value for sbuf.st_mode. Is it possible mode_t is too small? It also may be that the configuration script sets some #defs that mess with system defines, I guess. I'll keep plugging.
