<?
   print(sprintf("%s", ""));
?>

I should note that this is intermittent, though hitting reload a bunch of times seems to cause it to happen reliably.

---

The above code fragment embedded in any script will cause the described behavior.  For example:

<?
   print("XXX\n");
   print(sprintf("%s", ""));
   print("XXX\n");
?>

Sorry I didn't make the clear at first.

I am unable to reproduce this, but could you try checking
out the latest version of functions/formatted_print.c and
see if the problem persists?

First, it should be noted that this example should in fact
result in 'document contains no data' - it prints nothing!

If you can reliably reproduce a crash (i.e., run httpd -X,
hit a page that contains a printf() of an empty string
several times, and get that process to crash - please update
the bug report or submit a new one.  Note that after n times
of hitting the standalone httpd, it'll properly exit (n is
usually 30).
