// { dg-do assemble } // { dg-options "-O" } // GROUPS passed old-abort // gcc puts the array into a register, and then the store_bit_field () code // in expmed.c gets confused when it tries to store zero past the end of the // register (because the index is past the array bounds). It ends up calling // store_split_bit_field, which then aborts, because we don't have a split bit // field. // // Seems easiest to detect this case in the front end, i.e. access outside the // array bounds, and then force the array to be allocated on the stack instead // of a register. main() { char i[1]; i[1] = 0; }
