[Bug c++/16227] New: ICE, -Wall, initialisation of global array of aggregates

["jan at etpmod dot phys dot tue dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

The code below gives an ICE with today's CVS head when compiled with -Wall: 
 
jan@nbjapan:$ g++ -c -Wall t.cpp 
t.cpp: In function `void __static_initialization_and_destruction_0(int, int)': 
t.cpp:7: internal compiler error: Segmentation fault 
 
* If the array is an automatic variable instead, everything is fine. 
* If s is a const char* the problem disappears 
* Without -Wall everything is fine (!). 
* I looked at the .ii, reducing this case is a PITA. IIRC there are some 
automated means for that? Otherwise I will have to give it a spin myself.  
 
Here's the code. 
 
#include <string> 
struct A { 
        std::string s; 
}; 
A a[] = { "foo" };
