Hello,

I have tried the following small script variant out again for
the semantic patch language.

@display@
expression action;
expression* pointer, target, x;
identifier member, var;
statement is;
type t;
@@
(
*t* var = pointer->member;
|
*pointer->member;
|
*target = pointer->member;
|
*t* var = pointer->member(...);
|
*pointer->member(...);
|
*target = pointer->member(...);
)
 ... when any
     when != pointer = \( action(...) \| x \)
*if (
(    !pointer
|    pointer == NULL
)
    )
  is


The software “Coccinelle 1.0.8-00029-ga549b9f0” (OCaml 4.10.0) reports the 
following error messages
for an analysis approach on source files from “Linux next-20200306”.

Is such information worth for further clarification?
