Subject:	Desperate workaround for Git 64-Bit crashes
X-IsSubscribed:	yes

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....
