xfce4-terminal crashes if input arrives too soon after resize

[Boris Gjenero]

If I start with an 80x24 terminal, resize to 80x25 with printf("\e[8;25;80t") and then quickly send output via Ncurses, then xfce4-terminal crashes:
Vte-0.0:ERROR:/build/vte-jOPZPt/vte-0.28.2/./src/ring.c:370:_vte_ring_thaw_one_row: assertion failed: (ring->start < ring->writable)
Aborted (core dumped)

All the xfce4-terminal windows run in the same process. When you run it a second time from the command line, it just opens a new window in the old process and quits. So, if you want to view that error output, close all xfce4-terminal windows and start the program again from another terminal program, like xterm.

Adding a half second delay after the escape sequence makes the problem go away.

Yakkety's xfce4-terminal-0.6.3 used gtk2 and correspondingly an ancient vte-0.28. Zesty's xfce4-terminal-0.8.4 uses gtk3 and vte-0.44. As much as I recall, we had such a bugfix in vte. So I'm almost sure it's fixed in Zesty. Let me know if I'm mistaken and it's still broken there.

I'm not able to reproduce this in Zesty xfce4-terminal 0.8.4-1. So, it seems you're right and this has been fixed. Thanks!

As this appears to be fixed for you now, closing as fixed released.
