<div>
<pre>The managed name "_Z1fORi" is demangled by binutils as:
$ c++filt _Z1fORi
f(int&)
Here `ORi` translates to a "a rvalue-reference to lvalue-reference to int",
which is collapsed to a lvalue-reference to int under C++'s reference
collapsing rules.
However, LLVM's demangler doesn't collapse them:
$ llvm-cxxfilt _Z1fORi
f(int&&&)
which is an invalid function signature.</pre>
