Bug#898960: [libpangoft2-1.0-0] Crashes some Java applications in pango_fc_font_key_get_variations

[gisl]

Is it still an option to backport the patch? Applications are still 
crashing...

Thanks

Will do.

OK.

That would be great!

Please preserve the subject line when replying to old bugs - Debian
contributors will often receive only your mail, out of context, and
have to look up the bug number to find out which package and which
bug you're referring to.

pango 1.43 is a new development branch, and at this point Debian
testing is in (very) hard freeze, so that new version is not suitable
for packaging for testing/unstable yet.

It might still be possible to backport the changes that fixed the bug,
or other strictly targeted, non-intrusive bug fixes. Linking to the
upstream release notes is less useful for this than linking to the
actual change. Am I right in thinking that the relevant change is
https://gitlab.gnome.org/GNOME/pango/merge_requests/12/diffs and this
is sufficient to fix the crash?

Thanks,

I am also experiencing this with eclipse, it seems there is a fix upstream,
see the discussion here: https://github.com/gentoo/gentoo/pull/10417

Thanks for the quick reply. In my case it's not a Debian-packaged application. 
It's an Eclipse-based IDE with many plugins.

It crashes deterministically with libpangoft2-1.0-0_1.42.1-1_amd64.deb
Reverting this to libpangoft2-1.0-0_1.40.5-1_amd64.deb fixes the crashes.

If there's any information I shall provide or anything I can do, just let me 
know.

Please list specific applications that crash so that we can try to
duplicate the issue here.

I've seen several examples recently where installing packages from the
deb-multimedia repo breaks Debian. For instance,
