chrisbra left a comment (vim/vim#18953)Hm, that indicates an overflow. Looking at your reproduction:
dd if=/dev/zero bs=1M count=10240 | tr '\0' 'A' > bigline.txt
that indicates 1 single line of 1,048,576 bytes * 10,240 = 10,737,418,240 bytes (without newlines).
colnr_T is int. So are you using 32bit arch? Don't you see an error message for such a long error with your patch?
I guess it makes sense. @zeertzjq what do you think?
