Just need to come up with a complete test. With my patch the following runs to completion: program foo integer :: cnt = 0 1 call bar(*10, *20) cnt = cnt + 1 goto 30 10 cnt = cnt + 1 if (cnt /= 3) call abort stop 20 cnt = cnt + 1 30 goto 1 end program foo subroutine bar(*, *) implicit none integer, save :: i = 0 if (i < 0) return 1 if (i > 0) then i = -i return 2 end if i = i + 1 end subroutine bar Having never used type bound procedure, it may take a bit to convert this into a testcase. ^ permalink raw reply [flat|nested] 9+ messages in thread

The patch cures the ICE in comment #1. I've attached two test programs. The 1st one does not use TBP. The 2nd one does. I get gfc6 -o z gfc6 -o z alternate_return_2.f90 && ./z alternate_return_2.f90:30:17: call argh%bar(*10, *20) 1 Error: Syntax error in argument list at (1) The reason is that whoever write the TBP code did not consider the possibility of alternate return. I don't blame them. I simply don't know how to fix it. ^ permalink raw reply [flat|nested] 9+ messages in thread
