urm, first of all, on my box, setting  buf[0] = '\0' worked fine for me,
second why aren't you using dup2() to get proper semantics
on stderr so that it goes to the same place as stdin?

hint:

#include <unistd.h>

...
#ifdef CGI_DEBUG
	         dup2(STDOUT_FILENO, STDERR_FILENO);
#endif /* CGI_DEBUG */
...
