Looks like the viminfo file needs some entries pointing to Xfile1
to reproduce this issue. The following commands reproduce the issue:
<place the above Test() function in a file called test.vim>
vim --clean -c 'set viminfofile=' -c 'call writefile(["aaa", "bbb",
"ccc"], "Xfile1")' -c 'edit Xfile1' -c 'normal 3Gyy' -c 'call
delete("Xfile1")' -c 'q'
vim --clean -c 'set viminfofile=' -c 'source test.vim' -c 'call Test()'
