NB, this was partially fixed in gnulib in 2009:
http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=b06da86eb05ed57e2861061ae5cacf4c7a3686f1
But glib has its own copy of this code, which hasn't been updated since 2008.
Embedded code copies are terrible, people really need to start removing them, or at least learning how to update them.
