[SOLVED] Segmentation fault in DVD Styler (core dump)

MickeyRat · 2022-10-31 12:36:28

I've done a few updates since I used DVD Styler so not sure where to look. Now when I use it, it core dumps with a segmentation fault. The only recent segmentation fault posts I'm seeing deal with readline and bash. It doesn't appear to be the same thing.

Here's the first error from the journal:

dvdstyler[1145]: segfault at 84d2b0 ip 00007f828d4afb4e sp 00007f8278acba70 error 4 in libc.so.6[7f828d43b000+15b000]

In the terminal I see the following errors:

(dvdstyler:3902): Gtk-CRITICAL **: 08:08:44.191: gtk_distribute_natural_allocation: assertion 'extra_space >= 0' failed

(dvdstyler:3902): Gtk-WARNING **: 08:08:44.192: Negative content width -5 (allocation 2, extents 4x3) while allocating gadget (node toolbar, owner GtkToolbar)

Segmentation fault (core dumped)

Anyone have any idea. Thanks

Segmentation fault (core dumped)

https://wiki.archlinux.org/title/Core_d … _core_dump

Assertions about the GtkSpinButton size likely relate t oyour gtk theme and/or the font used, but it's not even clear whether that's what causes the segfault (since it's not a SIGABRT)

Thanks that's very interesting. I've never encountered coredumpctl. I may have to do some digging into that utility. I was a DBA before I retired so I've seen debuggers before. The cordumpctl info was pretty long and, to me, not that informative. I'll put it up on pastebin, if you think it'll help.

I'm posting all the output from coredumpctl gdb because there are some warnings before I entered the bt command that I'm not sure about. My reading of that output indicates a problem in libc.so.6 but, we're into unfamiliar territory for me. So perhaps libwx_baseu-3.2.so.0 or something else entirely.

Thanks again for the informative reply.

Edit: I took it a litlle farther to see what owned those libraries. libc.so.6 is owned by glibc which was last updated on 10/7. libwx_baseu-3.2.so.0 is owned by wxwidgets-common which was last updated 9/9. I've used DVD Styler sucessfully since both those updates.

The segfault in libc is because of a memory corruption ("free" is used on non-allocated RAM etc, it's unlikely that "free" itself has the bug)
libwx_baseu-3.2.so.0 would be from https://archlinux.org/packages/extra/x8 … ts-common/ but it merely starts a thread and the problem then occurs inside three private/unexported/stripped functions in dvdstyler
There unfortunately isn't much to learn from this.

For a quick test, move away ~/.dvdstyler and ~/.config/dvdstyler

Edit: the inbetween is https://archlinux.org/packages/community/x86_64/wxsvg/ which was updated 2022-10-22

Moving the DVD Styler configuration file didn't change anything but, downgrading wxsvg took care of the problem. I'll keep an eye out for updates of wxsvg or DVD Styler and upgrade when appropriate. Thanks!!!

Edit: I get the impression that you are involved in support for at least something here. This is probably a known issue but, if I can help isolate it, please reply here. I appreciate the help.
