Description Marcin Cieślak 2020-01-11 12:02:48 UTC
This is FreeBSD 11.3-STABLE #0 r356413 on amd64 laptop,
after 11.3 update all packages reinstalled with pkg.

I had a relatively unclean installation of gimp 2.8 which had to be removed manually, I have also deleted $HOME/.gimp and $HOME/.config/GIMP

gimp crashes on startup:

glib version is glib-2.56.3_6,1

Potential upstream issue:

Comment 2 Marcin Cieślak 2020-01-11 15:06:13 UTC
unlikely to be    
https://gitlab.gnome.org/GNOME/gimp/issues/4392 since our glib is older

The brush seems to come from

/usr/local/share/mypaint-data/1.0/brushes/classic/blend+paint.myb

and belongs to

$ pkg which /usr/local/share/mypaint-data/1.0/brushes/classic/blend+paint.myb
/usr/local/share/mypaint-data/1.0/brushes/classic/blend+paint.myb was installed by package mypaint-brushes-1.3.0

jq confirms this is a valid JSON file.

This could be the following assertion in json-c library:


        assert(json_object_get_type(jso) == json_type_object);


https://github.com/json-c/json-c/blob/json-c-0.13.1-20180305/json_object.c#L476
Comment 4 Marcin Cieślak 2020-01-12 22:00:56 UTC
tried side stepping through the function:

it seems that json_object_get_type() gets loaded from 

/usr/local/lib/libjson-glib-1.0.so.0

> pkg which /usr/local/lib/libjson-glib-1.0.so.0
/usr/local/lib/libjson-glib-1.0.so.0 was installed by package json-glib-1.4.4

Both are referred to from the gimp binary:

> ldd /usr/local/bin/gimp-2.10 |grep json	
        libjson-glib-1.0.so.0 => /usr/local/lib/libjson-glib-1.0.so.0 (0x804c93000)
	libjson-c.so.4 => /usr/local/lib/libjson-c.so.4 (0x805e0a000)


radziecki> objdump -T /usr/local/lib/libjson-c.so.4 | grep json_object_get_type
0000000000005240 g    DF .text	000000000000002d  Base        json_object_get_type
radziecki> objdump -T /usr/local/lib/libjson-glib-1.0.so | grep json_object_get_type
0000000000014d70 g    DF .text	000000000000005b  Base        json_object_get_type


wow.
Comment 5 Marcin Cieślak 2020-01-12 22:50:29 UTC
Filed https://gitlab.gnome.org/GNOME/gimp/issues/4491 with gimp and also https://github.com/json-c/json-c/issues/534 with the json-c library.

Probably those libraries should CONFLICT with each other, but then we will not be able to build gimp :/

Comment 7 Marcin Cieślak 2020-01-13 00:41:04 UTC
This bug seems to be reproduceable only if json-c is built without -O2 (I was using WITH_DEBUG=yes which removes -O2), see https://gitlab.gnome.org/GNOME/gimp/issues/4491#note_684094
Comment 8 Marcin Cieślak 2020-01-13 12:35:41 UTC
(In reply to Marcin Cieślak from comment #0)
The original crash as reported in the comment #0 was a different thing. I got this heisenbug when building everything WITH_DEBUG set to true. The original crash was there because unpackaged /usr/local/lib/babl-0.1/16bit.so was there as a leftover from the previous gimp installation.

Therefore this bug reports concerns the second json-c related crash only.
