--- Comment #4 from Jakub Jelinek  ---
Somehow convert_template_argument is called with TEMPLATE_PARM_INDEX, even when
processing_template_decl is 0, which results in it not to be considered
dependent, while the constexpr.c code doesn't expect it to appear.

I am compiling with:
g++ test_bug.cpp -o test_bug
g++ -std=c++11 test_bug.cpp -o test_bug
g++ -std=c++14 test_bug.cpp -o test_bug
and it fails in the 3 cases.

Both snippets started to be rejected (ICE) with r223301.
One has to use -std=c++11.
