--- Comment #14 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > But I guess even this doesn't help, while it will help poor man's flexible > array members in C/C++, in this Fortran case the problem is that there is > COMMON /FMCOM/ X(1) > in this TU, while > COMMON /FMCOM / X(1000000) > in some other TU, and get_ref_base_and_extent caps maxsize at > DECL_SIZE - bit_offset (which is generally right, but Fortran COMMON > is just weird). This invalid Fortran. > So, perhaps we want some flag on the Fortran COMMON decls that would be > set on COMMON that ends with an array and would tell get_ref_base_and_extent > (and other spots?) that accesses can be beyond end of the decl? Related to/ duplicate of pr44882?
