C-h f file-truename says

file-truename is smart enough to detect symlink loops (it has a counter
that starts at 100 and decrements on every dereference: if it ever gets
negative, watch out) and recursion seems to occur when it steps to the
parent directory and tries to find *its* truename - but there seem to be
adequate safeguards to prevent bottomless recursion (e.g. the remaining
counter is passed to subsequent calls).

It might be a good exercise to start with whatever file it's failing on
and then look at both it and all its parent directories (with ls -l if
you are on Linus/OSX/BSD/other Unix variant), taking a jaundiced look at
any symlinks you find on the way.
