testcase

I (unsuccessfully) tried passing a lambda as a template-parameter and resorted
to reinterpret_casting it to a normal function-pointer, which caused an
internal compiler error and gcc telling me to report it.

Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

I've attached test.cpp, which is very short and has almost the same contents as
test.ii anyways.
