seeing this too. Seems to be a race in | static int http_request(... | run_active_slot(slot); | ret = handle_curl_result(slot); On fast or cached connections, run_active_slot() can download the pack completely, frees 'slot' and starts download of objects immediately by using the allocated 'slot' object. handle_curl_result() expects the original 'slot' and crashes. Explanation is not correct, but problem is run_active_slot() -> finish_active_slot() -> process_object_response() -> start_object_request() -> start_active_slot() call chain https://github.com/git/git/commit/88097030725bf68d1801559cfb4785b93a50f5f8 is responsible for the crash (formerly, the 'results' on stack very used, now the 'results' within the slot object which are modified by the call chain above). I ran the following: $ git clone http://oss.tresys.com/git/refpolicy.git Cloning into 'refpolicy'... It only ran for a second or so with the message above, then crashed. backtrace_rating: 4 Package: git-1.7.11.7-1.fc17 OS Release: Fedora release 17 (Beefy Miracle) I invoked git pull on a repo that was cloned before the latest git update from a http url. I also tried to clone again, doesn't work either. backtrace_rating: 4 Package: git-1.7.12.1-1.fc18 OS Release: Fedora release 18 (Spherical Cow) Running the following command caused the problem: git clone http://gnuradio.org/git/gnuradio.git I can replicate the error in a Fedora 17 i686 VM (Virtualbox 4.2.4 r81684) as well as on my native i686 Fedora 17 install. This Fedora Forums post covers the problems I see on my system accurately: git clone http://gnuradio.org/git/gnuradio.git Information from my syslog: Nov 13 09:16:41 blue kernel: [ 5014.537033] git-remote-http[7360]: segfault at 0 ip 0804e783 sp bf9bada0 error 4 in git-remote-http[8045000+9b000] Nov 13 09:16:41 blue abrt[7362]: Saved core dump of pid 7360 (/usr/libexec/git-core/git-remote-http) to /var/spool/abrt/ccpp-2012-11-13-09:16:41-7360 (10207232 bytes) backtrace_rating: 4 Package: git-1.7.11.7-1.fc17 Architecture: i686 OS Release: Fedora release 17 (Beefy Miracle) The same problem here: git clone http://luajit.org/git/luajit-2.0.git git-1.7.11.7-1.fc17.i686 git-1.7.11.7-2.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/git-1.7.11.7-2.fc17 Package git-1.7.11.7-2.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days.
