Any check for multiply declared and initialized variables (actually doesn't happen)

[Steve Albright]

We came across this in our code

int column, row, index;
column = index = row = 0;

so I did a search and found this topic, only the last variable gets initialized

I can't access that link, but why would this not initialize all three variables?
Seems to work just fine: https://godbolt.org/z/T88e61s6h

Updated link, maybe there are compiler differences but I'd hope not...
