The openSUSE Tumbleweed packages are now built with -D_FORTIFY_SOURCE=3. We received a downstream report about a similar error: After upgrading Tumbleweed lately, kdenlive crashes when loading the first clip. DRKonqi does not produce crashinformation. I started kdenlive with gdb and got the following: /////////// found list (QUrl("file:///home/xxxxx/Videos/2012Suriname/20120719-083840.mp4")) /////////// creatclipsfromlist (QUrl("file:///home/xxxxx/Videos/2012Suriname/20120719-083840.mp4")) true "-1" /////////// createClipFromFile "/home/xxxxx/Videos/2012Suriname/20120719-083840.mp4" "-1" === GOT DROPPED MIME: "video/mp4" /////////// final xml "<producer>\n <property name=\"resource\">/home/xxxxx/Videos/2012Suriname/20120719-083840.mp4</property>\n</producer>\n" [New Thread 0x7fff59a2b640 (LWP 25561)] ============STARTING LOAD TASK FOR: "/home/xxxxx/Videos/2012Suriname/20120719-083840.mp4" ::::::::::::::::::: /////////// creatclipsfromlist return false *** buffer overflow detected ***: terminated Thread 31 "Thread (pooled)" received signal SIGABRT, Aborted.
Hello, Can't you get a more detailed crash backtrace? It would help to debug... In the meantime you may continue to work with AppImage or Flatpak.

Thanks Freek! So it seems to come from MLT in producer_avformat_init... Is it difficult to get debug symbols so that we get the line? Then maybe forward to MLT...
Created attachment 149943 [details] back trace with more debuginfo included Is this what you are looking for?
Looks like this is a bug in glibc, fixed with https://github.com/bminor/glibc/commit/9bcd12d223a8990254b65e2dada54faa5d2742f3 (confirmed locally).
If you cannot wait for the glibc fix, either build mlt with _FORTIFY_SOURCE=2, or switch to libmlt 7.8.0, that contains a fix for this crash. openSUSE TW users can use my libmlt build from here: https://build.opensuse.org/package/show/home:frispete:blender/libmlt until this is accepted for multimedia:libs. If you do so, provide feedback, please!
