This may not be a bug, but I hope it will be fixed.

      CALL A
      END

      SUBROUTINE A
      INTEGER I(33554432)
      I(33554432) = 0
      END

I can compile and execute the program successfully like:

> g77 test.f
> ./a.out

But if I add SUBROUTINE B, it fails with 'Segmentation fault'. 

      CALL A
      CALL B
      END

      SUBROUTINE A
      INTEGER I(33554432)
      I(33554432) = 0
      END

      SUBROUTINE B
      INTEGER I(8388608)
      END

Even if I do not call B, it fails with 'Segmentation fault'. 

      CALL A
      END

      SUBROUTINE A
      INTEGER I(33554432)
      I(33554432) = 0
      END

      SUBROUTINE B
      INTEGER I(8388608)
      END

My environment is
