https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80536 --- Comment #8 from Jakub Jelinek --- But we ideally shouldn't be folding anything until we actually c_fully_fold or cp_fold recursively, starting with the leafs. Most of the folders heavily rely on that.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80536 --- Comment #7 from Marek Polacek --- I.e. I'm worried we could trigger the endless recursion also if we happen to call fold() on that expression via a different path than from save_expr.
