Hi
I'm using the libxml2 2.7.7 with zlib 1.2.5 in a
slackware64-current system and i'm having crashes in firefox
and in claws-mail RSS feeder plugin.
in both cases i see that libxml2 is called then zlib,
returning a crash. Downgrading zlib and libxml2 to the last
stable slackware release the problem disappears (libxml2 2.7.6
and zlib 1.2.3).
Here is a trace of the firefox crash:

please note that /usr/share/mime/application/x-gzip.xml isn't
compressed, so i don't know why zlib is called.
So is there any known or new problem of libxml2 2.7.7 with zlib
1.2.5? or should i try to build zlib with debug and report back?
Thanks in advance

Naturally the common people don't want war... but after all it is the
leaders of a country who determine the policy, and it is always a
simple matter to drag the people along, whether it is a democracy, or
a fascist dictatorship, or a parliament, or a communist dictatorship.
Voice or no voice, the people can always be brought to the bidding of
the leaders. That is easy. All you have to do is tell them they are
being attacked, and denounce the pacifists for lack of patriotism and
exposing the country to danger. It works the same in every country.
-- Hermann Goering, Nazi and war criminal, 1883-1946
