+Large outputs may cause trouble.  On Solaris 8 through 10, for example,
+the command @samp{/bin/printf %010000x 123} dumps core.  This particular
+bug should have little practical effect since Solaris shells' builtin
+@command{printf} commands do not have the bug, but it indicates an area
+that other @command{printf} implementations may have trouble in.
