The ptyp command returns inconsistent types for the c '/'(BINOP_DIV)
operator:
(gdb) ptyp 3 / 2
type = int
(gdb) p 3 / 2
$4 = 1
(gdb) ptyp 3.0 / 2
type = double
(gdb) p 3.0 / 2
$5 = 1.5
(gdb) ptyp 3 / 2.0
type = int
(gdb) p 3 / 2.0
$6 = 1.5
I suspect that this bug is due to the fact that
the type of this binary operator is inferred from the
left node type, but this is wrong in the case '3 / 2.0'
