[bug-gettext] [bug #47847] Undefined behavior [use-after-free] possible in libgettext

[Daiki Ueno]

Follow-up Comment #1, bug #47847 (project gettext):

Thanks for pointing that out.

> A reasonable fix is to convert the pointers to be compared to uintptr while
both pointers are still valid

It sounds like a good idea, but I doubt we can always assume that uintptr_t is
available.  So, I have created a patch to fix it by postponing free:
https://lists.gnu.org/archive/html/bug-gnulib/2016-05/msg00016.html

Does it make sense?
