Test case

Got this while triaging #57498. The test program is clearly wrong, but since
ICEs should always be reported ...

% g++-4.7 -O test.cpp 
test.cpp: In destructor 'foo::~foo()':
test.cpp:7:3: warning: 'noreturn' function does return [enabled by default]
test.cpp: In function 'int main()':
test.cpp:14:1: internal compiler error: Segmentation fault
