Hello
I've been attempting to use Cygwin's Git version 2.1.1 to manage pictures on
my 32-bit PC and my 64-bit laptop, both running Windows 7. I downloaded the
correct 32/64-bit version of Cygwin on both machines. In my pictures folder
on my PC, I created a git repository and did an "git add .", etc., and then
created a bare repository which I then attempted to clone on my laptop. It
cloned, but did not include all the pictures. I redid the "git add .",
commit, and push on my PC, and then redid the pull on my laptop, but it
still was missing some pictures. Per advice from the internet, I then did a
"git reset --hard FETCH_HEAD" on my laptop, and that is what caused the
Segmentation fault (core dumped)4007). I repeated all of my steps, and the
segmentation fault happened again each time, so I don't think it was a
fluke.
Here's the git.exe.stackdump output:

I tried debugging it with gdb, but without the symbol table, I don't think
it will help much:

Also, commits are in some cases taking in excess of 20 minutes, both at home
with my pictures folder, also at work with a large repository. Surely
something can be done about this.
thanks
