Description of problem: 

following test piece of code (randomly generated C - are those two '!' even 
valid?) makes GCC ICE. 

int main(){
    float c2 = 1.0;
    if ( ! ! c2 * 07ll == 0 ){
    }
}

Version-Release number of selected component (if applicable):
gcc-4.3.0-8.i386

How reproducible:
seems to be reproducible only in 32-bit mode, and without optimizations

Steps to Reproduce:
1. gcc t.c
  
Actual results:
ICE

Expected results:
no ICE

Additional info:
I tried this with RHEL5 and upstream gcc (HEAD cca month back), both were 
affected too.
