Hmm. That's still not conclusive. I had expected the program to stop at
vasnprintf.c:4635 twice, once with result = "0.000000" and then with
"0.000000 33".
Needs more single-stepping. Where does the "0.000000" string definitely come
from? From the system, I suppose?
You can also try a standalone test program, linked against the system's
sprintf(), like this:
===============================
#include <stdio.h>
int main()
{
char buf[100];
sprintf (buf, "%Lf", -0.0L);
printf ("%s\n", buf);
return 0;
}
===============================
