Bug#676423: doxygen: new segmentation faults in version 1.8.1-1
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Dear Matthias, I see that you have included my patch in an upload together with a lot of other fixes, including a new upstream and I thank you for that. However, that certainly means that your new upload will not reach Wheezy. What is your plan to fix this bug in Wheezy? Is that fine for you if I upload an NMU (1.8.1-1+nmu1) to testing-proposed-updates? Kind regards, Thibaut. -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBCAAGBQJQCw7xAAoJEJOUU0jg3ChAfUgQAMfELzlnXjcTUKptiYOP3zmn qRKFnw2onlXGSugvRoVpyBIEObecikfvZtocwR0lNpLR8s2fKoZ6NeXxFmkEdPew 9yNX3vkY+v/Ic0YXsS0n75k1usu9GzCYk5XapDsJWE0tPy03I74wDW0eWBg0R4xf iTMGQm8AltqUw29uL8032DPNNOWDbsnP6MQoBCZLIkHadiy+r5hvz7mC8cF25pwR vNfAeZIvGeEmMaKtqYaA45qtLpK2FDhDwrlzJIQ9xjX1+I9AiYZ9klcR02yBDYyJ 9yCGLVM3aGpssdGWbv4t9ixt4tzE7TSYXL3lI3ZGaTd7msVETqSz4jMQd8VfOm3M 9im6ujZCVwAlwulbiU6DrL8kjJIhjaSuOrE2c6oeg0CtZEKx+MDwj1ongWqKStvP 5TLUrn9an0bEuR9kF4dEuEE23wsSBdPOf1nzlfvurtWm+NuA7qRYdhUwE5U9wjp3 iUvBMShvLZg50GFI6HbaUG8T6ZEtfzeDFUiXXUdGMerxphv1yc9cy0peWCDwCFJt iZAdu5vkZ4tiq3GtGGIxh/wGiHmO+8hIi80buDzEum4zScgm9nlFY3iy0hz8wZ3G sqPm6UGTlUp1xu0dpueIpZYZxO+WbDfBbeIc8J//wmmXSQRwh+ExYFXLdKo5GeZj KkCV7QQCNMVqWFakjwX1 =hYrx -END PGP SIGNATURE- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#676423: doxygen: new segmentation faults in version 1.8.1-1
Package: doxygen
Version: 1.8.1-1
Severity: important
Hi,
Previous verison (1.7.6.1-2.1) in Debian works fine (I saved the package).
Version 1.8.0 in Gentoo Linux works fine too.
Now in Gentoo doxygen also has version 1.8.1 by default, and it fails with
the same backtrace. So I believe new bug comes from upstream.
How to reproduce:
1) I found this problem when I was trying to rebuild my package with new
doxygen:
$ export LC_ALL=C
$ dget -x
http://mentors.debian.net/debian/pool/main/l/leechcraft/leechcraft_0.5.70+dfsg-1.dsc
$ cd leechcraft-0.5.70+dfsg/
$ dpkg-buildpackage -rfakeroot -A
...
Generating code for file cut/src/interfaces/core/icoreproxy.h...
Segmentation fault
make[1]: *** [override_dh_auto_build-indep] Error 139
...
2) More common way to reproduce this problem:
$ git clone --depth 1 git://github.com/0xd34df00d/leechcraft.git leechcraft-git
$ cd leechcraft-git/doc/doxygen/core/
$ gdb doxygen
(gdb) run Doxyfile
