Sorry, you're right. My shell messed up the symbol. When I quote it
c++filt still crashes.

This is what it should look like:

std::remove_reference<int&&>::type&&
std::move<trompeloeil::call_modifier<mock_c, trompeloeil::matcher_info,
trompeloeil::throw_injector<trompeloeil::call_modifier<trompeloeil::call_matcher<int
(int), std::tuple<trompeloeil::predicate_matcher<auto
