There is `v:key`, do not use `index()` here; and using `copy()` in
`index()` is not needed. And I am unable to reproduce your problem
(vim 8.0.582), maybe need a specific set of options or specific file
contents: using file created with `writefile(range(10),
'/tmp/filename')` for the test.
Wondering whether you understand that without the context (is this
placed in a function?) `g:file` and `file` are the same variables?
(Inside a function `file` would be `l:file`.) Though based on my
knowledge of VimL this should not matter in this code: `file` will be
reassigned only after expression evaluation finishes.

Works fine for me (spaces added for readability):
let file = ['aaa', 'bbb', 'ccc']
echo map(copy(file), 'v:val . ":" . index(copy(file), v:val)')
['aaa:0', 'bbb:1', 'ccc:2']

Reproduce it with a list made of 15 lines of a file.
But effectively I have to use v:key.
Thank you for all.

Ok works fine with v:key.
let file = readfile(expand("%:p"),'b')
call map(file,'v:val.":".v:key')
nota : g:file was just to put=g:file result in my buffer to see the result.
Thank you !
