      Description

      (I have not verified, but I think it's a regression)

      Example program:

      #include <stdint.h>
       
      typedef union Test {
          struct TestBit {
              uint32_t value0: 1;
              uint32_t reserve0: 7;
       
              uint32_t value1: 1;
              uint32_t reserve1: 23;
          } bit;
          uint32_t word;
      } Test;
       
      int main(void)
      {
          Test t = {{0, 0, 0, 0}};
          t.bit.value1 = 1;
       
          return 0; // break here
      }

      Expected: the values for the bit fields are shown.

      Note that it does work if uint32_t is replaced by int.
