[Bug c++/14203] [3.4/3.5 regression] ICE on warning about unused variable

["bangerth at dealii dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Additional Comments From bangerth at dealii dot org  2004-02-19 00:26 -------
Confirmed. Here's something a little smaller: 
----------------------- 
int* foo();  
const bool b = false; 
 
int main() {  
  int i;  
  
  if (b)  
    if (int* p = foo())  
      {  
        int bla; 
        i = 1;  
      } 
} 
------------------------ 
 
This is a regression on 3.4 and mainline against 3.3.3: 
deal.II/base> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc -Wall 
x.cc: In function `int main()': 
x.cc:10: warning: unused variable 'bla' 
x.cc:8: warning: unused variable 'p' 
x.cc:13: internal compiler error: in make_decl_rtl, at varasm.c:707
