- Authentication-results: sourceware.org; auth=none
Last Cygwin core update introduced disastrous (i.e. for me) Git bugs,
where some commands instantly crash, e.g.:
% git gc
error: pack-refs died of signal 11
error: failed to run pack-refs
Tried rebasing, reinstalling Git, no help. Used "strace" to help
identify executable "/usr/lib/git-core/git" as the problem: executing it
in a shell with no arguments resulted in an immediate Segmentation
Violation (executing "strace /usr/lib/git-core/git" worked fine).
Surprisingly, "/bin/git" was a hard-link to the same file and started up
fine (suggesting executable name/location dependencies). In
desperation, executed
% cd /usr/lib/git-core
% rm git
% ln -s /bin/git
and, amazingly, "/usr/lib/git-core/git" now executes and high-level
commands are working again. Can't explain, but wanted to pass this
strangeness on -- see log below....
