Maybe.  There are workarounds, as I detailed in a message to bug-readline
in June.

Another problem is that gnulib has significantly expanded the scope of
the xmalloc/xrealloc/xfree interface.  The source file that defines
those also defines half a dozen other functions: x2realloc, xzalloc, etc.
It also calls those functions internally, requiring the source file to be
linked in whether or not the application calls any of them directly.  I
don't consider this good interface design.  Readline defines only
xmalloc/xrealloc/xfree.  That's an acceptably small footprint, though I
could also see adding xcalloc.
