[Bug c++/33620] [4.3 regression] internal compiler error: canonical types differ for identical types const QList<QStringList> and const QList<QStringList>

This is the shortest I can come up with:
----------------------
template <typename T>
struct __attribute__((visibility("default"))) List {};

int bar(List<int> args);
bool test(const List<int> &);

int i = bar(List<int>());

bool test(const List<int> &) {}
---------------------
tmp/bangerth> /tmp/bangerth/bin/gcc-mainline/bin/c++ -c x.cc
x.cc: In function 'bool test(const List<int>&)':
x.cc:9: internal compiler error: canonical types differ for identical types
const List<int> and const List<int>
