[bug-gettext] Bug#608181: /usr/bin/xgettext: xgettext segmentation fault (fwd)

[Santiago Vila]

Hello.

I received this report from the Debian bug system.

I asked the submitter for a way to reproduce it and he sent me a
tarball including all the required files, so I have made this short
recipe to reproduce the segfault:

wget http://people.debian.org/~sanvila/bug-608181/wp-mini-gettext-pb.tar.bz2
tar xjvf wp-mini-gettext-pb.tar.bz2 
cd wp/wp-content/languages
./extractpo.sh

Thanks.

Subject: Bug#608181: /usr/bin/xgettext: xgettext segmentation fault

Package: gettext
Version: 0.18.1.1-3
Severity: important
File: /usr/bin/xgettext

Hi,

While trying to extract translatable strings (from WordPress), I get
a Segmentation fault.

I use the following command:

xgettext --width=80 --from-code=utf-8 \
        --keyword=__ --keyword=_e --keyword=esc_attr__ --keyword=esc_attr_e \
        --keyword=esc_html__ --keyword=esc_html_e \
        --keyword=_x:1,2c --keyword=esc_attr_x:1,2c
        --keyword=esc_html_x:1,2c \
        --keyword=_n:1,2 --keyword=_nx:1,2,4c \
        --keyword=_ex:1,2c \
        --keyword=_n_noop:1,2 --keyword=_nx_noop:1,2,3c \
        --default-domain=wp \
        --language=php \
        --files-from=fichiersphp.lst \
        --exclude-file=cities.pot \
        --exclude-file=ms.pot \
        --output=wp.pot

If I remove the option "--exclude-file=ms.pot" (this file is extracted a
similar way), I've not the Segmentation Fault.

If I run it from gdb, I get:
Program received signal SIGSEGV, Segmentation fault.
