[BUG] - git-read-tree segfaults

Hi,

I was following the git core tutorial and git-read-tree got me segfault. I accidentaly executed the git-read-tree without "-m -u" options and got segfault.

I can reproduce with the latest git using following script.

----------------------------------------------- #!/bin/sh

GIT=$1

rm -rf crash; mkdir -p crash; cd crash $GIT init echo "xxx" > xxx $GIT add xxx $GIT commit -m "xxx" $GIT checkout -b yyy echo "yyy" > yyy $GIT add yyy $GIT commit -m "yyy" echo "yyy1" >> yyy $GIT commit -a -m "yyy1" $GIT checkout master echo "xxx1" >> xxx $GIT commit -a -m "xxx1" mb=$($GIT merge-base HEAD yyy) $GIT read-tree $mb HEAD yyy -----------------------------------------------
