Description of problem: gcm-viewer often crashes (as in 9/10 x), either from menu launcher or from terminal. when failing from terminal output is: gcm-viewer malloc(): unaligned tcache chunk detected Aborted (core dumped) (launchGUIs discovery, another one for Lewis, take a bow!) install from: Mageia-9-beta1-i586.iso DATE.txt: Mon Feb 6 06:53:03 PM CET 20 XFCE DE only Version-Release number of selected component (if applicable): How reproducible: very often, 9/10 x Steps to Reproduce: 1.install XFCE DE from above .iso 2.invoke gcm-viewer from terminal or *Colour Profile Viewer* launcher 3.
Gnome (Wayland and Xorg) also
(In reply to Ben McMonagle from comment #1) > Gnome (Wayland and Xorg) also If the summary and description of the package are correct, then only comment #1 matters $ urpmq -i gnome-color-manager Name : gnome-color-manager Version : 3.36.0 Release : 3.mga9 Group : Graphical desktop/GNOME Size : 3493897 Architecture: x86_64 Source RPM : gnome-color-manager-3.36.0-3.mga9.src.rpm Build Host: localhost Packager : papoteur <papoteur> URL : http://projects.gnome.org/gnome-color-manager/ Summary : Color management tools for GNOME Description : gnome-color-manager is a session framework that makes it easy to manage, install and generate color profiles in the GNOME desktop. [marja@DenkBlok4 ~]$ IMHO the above implies that it isn't supposed and tested to work in another DE. Apart from that, the URL is wrong, it should be https://gitlab.gnome.org/GNOME/gnome-color-manager Assigning to the GNOME maintainers, CC'ing papoteur.

Trying this on an up-to-date Cauldron system (which should reflect an updated installed ISO); I am finding that several of the desktops no longer start! Gnome both ways, Mate, at least. Where the desktop does start OK, gcm-viewer also starts OK: I think at least LXDE, Xfce, LxQt, Plasma.

installed all DE from i586 Mga9 beta CI. on reboot changed DM from GDM to LightDM, reboot and logged in to XFCE updated to latest. open a terminal and tried gcm-viewer: [work@localhost ~]$ gcm-viewer [work@localhost ~]$ gcm-viewer malloc(): unaligned tcache chunk detected Aborted (core dumped) [work@localhost ~]$ gcm-viewer malloc(): unsorted double linked list corrupted Aborted (core dumped) [work@localhost ~]$ gcm-viewer [work@localhost ~]$ gcm-viewer malloc(): unaligned tcache chunk detected Aborted (core dumped) [work@localhost ~]$ gcm-viewer malloc(): unaligned tcache chunk detected Aborted (core dumped) [work@localhost ~]$ gcm-viewer [work@localhost ~]$ gcm-viewer [work@localhost ~]$ gcm-viewer [work@localhost ~]$ gcm-viewer malloc(): unaligned tcache chunk detected Aborted (core dumped) [work@localhost ~]$ gcm-viewer malloc(): unsorted double linked list corrupted Aborted (core dumped) [work@localhost ~]$ gcm-viewer malloc(): unsorted double linked list corrupted Aborted (core dumped) gcm-viewer with no core dump launch successfully.

Hello, This kind of problems is of type memory overwrites. The program writes some data at a place it shouldn't. This is why the error isn't systematic. There is no new release since 2020. This error is not reported upstream. All that I can try is to rebuild it, to be sure it use the last libraries, what I will do. I can't try to debug it.
Thanks Ben for your convincing tests on Xfce. And Yves for an explanantion & offering to rebuild it. Note Ben's report is 32-bit. My tests were 64-bit. After papoteur's rebuild, can you Ben please re-try this for each desktop x32. One crash per desktop suffices. Tedious, yes; but less so than re-booting between them. I will re-run the x64 desktops. Need to wait for these results before judging what to do; at worst, drop the pkg.

Baptiste (new tester) ran a x86_64 all DE net-install ~ 9th Mar, after the beta1 rnd5 arrived for testing. he sent me a copy of his guiApps.txt, guiResults.txt and guiFails.txt. gcm-viewer was not listed, so it does appear to be arch specific.
info; when the application does launch successfully, attempting to select another profile type causes a: malloc(): unsorted double linked list corrupted Aborted (core dumped) installed from Live-Mageia9-beta1-Xfce-i586
My assumption is that the error is specific to 32bits arch. Something like the computation of the space of a structure which is different in 32bits than in 64bits. And it is not reported upstream because the usage of 32bits arch is small. To identify the problem, the tool valgrind is the way. https://valgrind.org/docs/manual/quick-start.html
Created attachment 13701 [details] valgrind output I installed a 32bits VM and I reproduce the problem. Thus I get a trace from valgrind. Culprit seems to be in liblcms2 Should we report that upstream?
I found this: https://github.com/hughsie/colord/pull/146 but we should already have and this: https://github.com/mm2/Little-CMS/issues/344 We should try to backport this: https://github.com/mm2/Little-CMS/commit/a9e4601ceb3a185d4f78cc0cfbd285cf0c399e9d
I applied https://github.com/mm2/Little-CMS/commit/a9e4601ceb3a185d4f78cc0cfbd285cf0c399e9d After updating to liblcms2_2-2.14-4.mga9.i586.rpm I get gcm-viewer running fine. I close this report. Reopen if this is not the case for you.
Resolution: (none) => FIXEDStatus: NEW => RESOLVED
Great work Yves.
Forgot to try it... $ rpm -q lib64lcms2_2 lib64lcms2_2-2.14-4.mga9 Just on Xfce, it starts fine as previously, and Ben's test comment 9 gave no trouble: all profiles could be selected.
Mageia-9-beta1-i586.iso DATE.txt: Mon Feb 13 12:37:07 PM CET 2023 single DE Xfce install. at initial desktop presentation: [work@localhost ~]$ gcm-viewer malloc(): unaligned tcache chunk detected Aborted (core dumped) update to system includes: liblcms2_2-2.14-4.mga9.i586 after updates applied: [work@localhost ~]$ gcm-viewer [work@localhost ~]$ manually closed application. selecting all profile types and tabs no longer crashes application. yet to check Gnome but looks good. Thanks
