				// { 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;				}
