Yes, without that it's not just that --enable-gcc-warnings is busted, it's that 
gnutls itself is busted when memory is low.

Apparently one is now supposed to do something like this:

gnutls_malloc = xmalloc;
gnutls_realloc = xrealloc;
gnutls_calloc = xcalloc;
gnutls_free = xfree;
gnutls_strdup = xstrdup;

although this does not appear to be documented.  What a pain.  Is that something 
you can test?  I don't have Fedora 21 installed yet.  (I think you'll have to 
define an xcalloc.)
