--- Comment #9 from marco atzeri <marco_atzeri at yahoo dot it> --- It seems the patch works, just not as I was expecting. The code allows to export the variables in the common block -------------------------- $ cat mydll-3.f90 ! mydll.f90 -- ! Simple library (to be compiled and linked as DLL/SO) ! subroutine print real :: x common /mydata/ x !GCC$ attributes dllexport :: x write(*,*) 'X = ', x end subroutine print --------------------------- With gcc-7.3.0 the test case fails as usual X = 0.00000000 In program: X = 1.00000000 with the patch it works. X = 1.00000000 In program: X = 1.00000000
