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.
