bug#69049: 29.2; Buglet in `read-from-string' (and, likely, `read') with defstructs.

[Marco Antoniotti]

Hi

Here is the problem.  This is in IELM.

ELISP> (cl-defstruct foo (msg "bar"))
foo
ELISP> (make-foo)
#s(foo :msg "bar")

ELISP> (make-foo :msg "baz")
#s(foo :msg "baz")

ELISP> (read-from-string "#s(foo :msg \"baz\")")
(#s(foo :msg :msg)
   . 18)

As you see, the structure is not read in correctly.

All the best

Marco Antoniotti
