--- Comment #16 from anlauf at gcc dot gnu.org ---
In the meantime Bill opened pr110419 and posted:

spawn [open ...]
 by value(kind=3D1): B
 by value(kind=3D1): A

Program received signal SIGSEGV: Segmentation fault - invalid memory refere=
nce.

Line 20 corresponds to

  call val  ("A",char(65))

which means that there should be a temporary holding the result of char(65)
which should be passed by value.=
