segfault: String would overflow textgrid. Truncating.

I built and installed revision ce028d2 via the AUR package. When I run it the window appears for a second then it crashes with the following error:

ERR<29523>:eovim /home/wmoore/aur/eovim-git/src/eovim-git/src/termview.c:860 termview_put() String would overflow textgrid. Truncating.
## Copy & Paste the below (until EOF) into a terminal, then hit Enter

eina_btlog << EOF

The backtrace looks truncated but running eina_btlog on the frames shown gives:

    /usr/lib/libeina.so.1| ??/??: 0 @ eina_log_print_cb_journald()
    /usr/lib/libeina.so.1| ??/??: 0 @ eina_log_print_cb_stdout()
    /usr/lib/libeina.so.1| ??/??: 0 @ eina_log_print()

The same crash also happens when running with -N. When run with -g 80x24 it does not crash.

Hi, I think there are two errors here:

• one from eovim, which has an issue when resizing at startup,
• one from the EFL (the underlying framework of eovim) which crash when printing the backtrace.

I've already experienced the EFL bug, but haven't pinpoint the version it is present in. What version of EFL are you using? An easy way to circumvent this issue while waiting for a fix in the EFL would be to disable the backtrace feature by setting EINA_LOG_BACKTRACE to something like -1.

The resizing bug in Eovim is a real problem, I'll work on that.

If you are using the GIT version of EFL, the segfaults should now be fixed.

Totally missed your original reply a week ago. Thanks for looking into a fix. I'll try it out when I'm back at work tomorrow.

Tried it out and it no longer crashes 🎉 Thanks.

Nice :)
