Hi,
just wanted to resurface this, it's still an issue for me. Every now and
then, almost every week, I have these crashes. Mainly one my laptop but
on my desktop too.
Just had three terminals crash on me at once (after interacting with
them each).
Arch linux, x86, with zsh 5.9-4. The traces are slighly different
(unfortunately no debug symbols). More or less the same zsh config as
previously. Hope this can shed some light on it and perhaps find a fix
(although zsh releases seems scarce nowadays).
Regards
Johan

Hm, I had cases where terminals have been on the same virtual desktop,

Not sure if SIGWINCH would be sent by just switching virtual desktop (sway).
One reason I'm speculating about this is because of this from your
previous stack trace:
#9 0x000055ff7ab040f8 zalloc (zsh + 0x730f8)
#10 0x00007fb08a549417 calclist (complete.so + 0x1b417)
#11 0x00007fb08a54b040 ilistmatches (complete.so + 0x1d040)
There's only one zalloc() in calclist:
ws = g->widths = (int *) zalloc(zterm_columns * sizeof(int));
If zterm_columns has somehow become messed up, this might run you out of memory.
Then in the other trace you have:
#10 0x000055d4aa005493 zhandler (zsh + 0xa8493)
#11 0x00007f2f935388e0 n/a (libc.so.6 + 0x3e8e0)
#12 0x00007f2f935fbef2 read (libc.so.6 + 0x101ef2)
That definitely means a signal was received, and SIGWINCH is
explicitly unblocked around that read() call, but it goes straight on
to:
#9 0x000055d4a9fc3874 zleentry (zsh + 0x66874)
The only way to get to that from a signal handler is when a
user-defined trap is run:
/*
* If zle was running while the trap was executed, see if we
* need to restore the display.
*/
if (zleactive && resetneeded)
