Comment: it seems it depends on file name, because when file is renamed it does not reproduce itself

IzV-Útěk_do_bezpečí.gz - file must have this name
Comment 3 Michal Hlavinka 2010-01-28 10:22:40 UTC 
it seems it's also enough to open empty file with the same name:

touch IzV-Útěk_do_bezpečí.gz

unzip will complain, but it will crash and abrt shows this crash as duplicate, so the problem is probably the same

because it seems it's caused by file name, here is my locale:

Comment 4 Jindrich Novy 2010-01-28 12:51:18 UTC 
Filed upstream: http://www.midnight-commander.org/ticket/1982

The failure happens when mc is trying to free gzip command line via g_free(p).

Upstream have a fix issue. Need to test.

Not all developers of mc have x86_64 arch (for example, at work my arch is i686), therefore I want ask to Jindrich: if this not hard to you - please, test branch 1982_segfault_on_gz_archive; and if bug fixed - vote into upstream bugreport (just add 'jnovy' into 'Votes for changeset' field). As ticketstarter you may vote.

> The failure happens when mc is trying to free gzip command line via g_free(p).    
Nope, failure happens at edit_get_filter() function (invalid calculation of malloc'ed memory).
