[bug-gettext] xgettext segmentation fault javascript

I get seg faults when running xgettext on _javascript_ files.

I've narrowed it down to ngettext and custom keywords.

Since we use keybased translations (monolingual) instead of english we've specified

--keyword=ngettext:1,1

This works, but only once per key, if I have more than one file with an ngettext call to the same key the seg fault appears with the following error:

*** Error in `xgettext': double free or corruption (fasttop): 0x0000000001af9d80 ***

To reproduce the error create two files, 'one.js' and 'two.js' with the following content in both files (one line):

ngettext('common.product.ucfirst', 1);

now, if you run

xgettext --keyword=ngettext:1,1 -o - one.js

xgettext --keyword=ngettext:1,1 -o - two.js

it works.

But if you run

xgettext --keyword=ngettext:1,1 -o - one.js two.js

I get a seg fault.

If you change one.js and two.js to use standard ngettext with ngettext('singular', 'plural', 2) and remove the --keyword it works.

I've tried this on fedora 20 with xgettext 0.18.3, 0.19.2 and 0.19.3 and on ubuntu 14.04 with xgettext 0.18.3
