Re: [Patch, fortran] PR37735 - Allocatable components in vectors of derived types cause ICE on assignment

But, I still don't see what distinction you're trying to draw between
-fbounds-check and -fcheck-size, because -fbounds-check correctly identifies the program is doing something that is possibly an error.

        REAL A(10,10)
        A = 1.0
        CALL SUB(A,10)
        END
        SUBROUTINE SUB(A, N)
        REAL A(N, N)
        PRINT*,A(1,N*N)
        END

With -fbounds-check, the above dies with a runtime error.  You then
fix your code:

Ah, yes - that's all real fine if that's the only not-really-wrong-but-non-conformant array indexing.

Unfortunately, in my world, the real bugs (read: addressing outside the extent of the array) are dwarfed by these non-bugs.

That's why I would like to have a separate option ...
