Segfaults - possibly ncurses related

[etenim]

I've yet to find out how it can be reproduced reliably, but when I exit from vim, after having worked on some file there seems to be a chance that wayst will segfault. There's also been segfaults when I use tmux, and both of these use ncurses.

Running wayst on a wayland compositor.

Here is the bottom parts of strace output leading up to a wayst terminal segfaulting when exiting vim:

I have another strace output, but from a segfault related to tmux this time. I entered "ctrl+b", and then "pgup" in tmux, and the segfault happened as soon as I hit "pgup" and any further attempts to reattach to that tmux session will segfault wayst.

It's looking likely that with vim it is related to usage of wayst's copy/paste functionality. I opened a c source file, and closed it again ":q" many times without managing to segfault wayst. However opening a c source file with vim just once and pasting text from the same wayst terminal, caused wayst to segfault when I entered ":wq" to save and quit vim.

I got another segfault doing the same thing again:

• cat c source file
• select random multiline chunk of text and yank (ctrl+alt+y)
• vim another c source file, enter insert mode and paste (ctrl+alt+p)
• save and quit ":wq"
• wayst segfaults

Using a wayland compositor.

[etenim]

I've reproduced it multiple times now (using the steps in my previous comment), and it is a consistent issue. There is however only segfaults when the copied contents is pasted into a vim running on the same wayst terminal the text is copied from. I tried copying and pasting between two different wayst terminals, and that did not cause a segfault.

I tried with "ed" instead of "vim" and did not get a segfault.

[etenim]

Strangely I'm not getting segfaults when copying text from a file viewed with "less". The segfaults happen always when I copy text from a file opened with "cat". It does not seem to matter what contents the file has, as long as "cat" is the program used to display it.

After having used "cat" to display text and then used ctrl+shift+y to copy the text, all I need to do is open and quit vim for wayst to segfault, pasting the text isn't even needed.

The "cat" utility is from busybox. I'll add that this is on a musl system, with a wayland compositor.

1. cat somefile
2. select text
3. ctrl+shift+y
4. run vim
5. quit vim
6. wayst segfault

Still couldn't reproduce this.

If you can consistently get it to crash, you can try to get some useful info by running a sanitized build: make -B mode=sanitized and just run normally.

Or get a backtrace from the coredump file:

• recompile with debugging symbols: make -B mode=debug
• crash the program
• start debugger (coredumpctl debug)
• print backtrace (at (gdb) prompt bt full)

Running wayst with debug symbols and gdb to capture a segfault.
