#<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug>

[Jean Louis]

I was using the module emacs-libpq for months
without problem. Reference:
https://github.com/anse1/emacs-libpq/issues/9

Now I have upgraded to the latest development
version of Emacs and am getting this bug below.

(["tlds_id" "integer" "nextval('tlds_tlds_id_seq'::regclass)" "" 1 #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> "" #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> "p" #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> "ID"] ["tlds_tld" "text" #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> "" 2 #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> "" #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug> #<EMACS BUG: INVALID DATATYP
 E (0x01) Save your buffers immediately and please report this bug> "x

Not even "SELECT 1" I can do without this bug
appearing.

If somebody have a clue, let me know.

Did you try recompiling the module against the new emacs-module.h?

Header of that module is here:
 #include <emacs-module.h>
 #include <libpq-fe.h>
 #include "pg_type.h"
 #include <stdio.h>
 #include <string.h>
 #include <stdlib.h>
 #include <assert.h>


Module emacs-libpq is here:
https://github.com/anse1/emacs-libpq/blob/master/pq.c

I am now trying to checkout some earlier version of Emacs to make it work. 

And I found out everything works fine in commit commit
1dff09739346037a588a3b9290800c09a9b3409a from Fri Feb 1 03:01:39 2019
+0300

Commit from March 1st 2019 did not work.

I will now try to move February 14th and let you know.

The latest commit that works successfully is:

a1c53d4294550380de76d6a6c4e29e9e8f6f9133

as from Tue Apr 16 14:33:24 2019 -0700

The dates after this one mostly segfaults when loading the module emacs-libpq or I get the bug.

I am trying to find some version newer than April 16th.

Can you try running Emacs with the --module-assertions option?

Without investigating in detail, the code at
https://github.com/anse1/emacs-libpq/blob/master/pq.c#L325-L326 is
clearly buggy, see https://phst.eu/emacs-modules#value-lifetime.

Re: #<EMACS BUG: INVALID DATATYPE (0x01) Save your buffers immediately and please report this bug>

[Jean Louis]

This is what I get on latest commit with Emacs. I do not know how to debug this.

emacs --module-assertion
Emacs module assertion: Emacs value not found in 11 values of 1 environments
Fatal error 6: Aborted
