Compiling the attached preprocessed code with gcc 4.3 svn rev. 128893
(regardless of compiler flags) results in

project.cpp:2826: internal compiler error: canonical types differ for identical
types const QList<QStringList> and const QList<QStringList>
Please submit a full bug report,
See <http://gcc.gnu.org/bugs.html> for instructions.


This breaks building Qt 4.x.

The error also occurs on powerpc64-linux with -m64, where a regression hunt
identified the following patch:

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>
Please submit a full bug report,

Sharad, what compiler version did you use for the new testcases?

This latest problem is identical to PR c++/35074, which has now been fixed. The
new test case in this bug is passing.
