The following code, in which the (contained) subroutine has an alternate return
argument which is not present in the subroutine call, produces a segfault:
------------------------------------------------------------------
debian-gfortran:~/test> cat altreturn3.f90
program altreturn3
call altret()
contains
subroutine altret(*)
return 1
end subroutine
end
debian-gfortran:~/test> ../bin-trunk/bin/gfortran altreturn3.f90 -o altret3
altreturn3.f90:0: internal compiler error: Segmentation fault
