["heinrich dot brand at fujitsu-siemens dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The function test returns 17 not 18 as required.

#include <stdio.h>

signed char test(long v[]){
 return ( ( ((signed char) (v[1] ?  0x100 : 0 ))) ?  17 : 18); 
}
    
int main(void){
        static long v[3];
        v[1]=2;
        printf("test : %d\n",test(v));
        return 0; 
}
