@myrrc thank you for the report! Just in case you have time - could you please try latest hstr version (2.5.0 is pretty old):
- either add my PPA: https://launchpad.net/~ultradvorka/+archive/ubuntu/ppa/+build/25988801
- alternative you can download
.debfrom launchpad https://launchpad.net/~ultradvorka/+archive/ubuntu/ppa/+build/25988801
Thank you!

Yes, the issue reproduces on the .deb you pointed me to.
Fresh master build `make CFLAGS='-O0 -g3'` does the same.
Looks like most interesting thing here is
```
#3 0x000055555555e2ba in loop_to_select () at hstr.c:1303
1303 c = wgetch(stdscr);
```
Unfortunately, I haven't been able to dig into ncurses despite
installing all debug packages.

Hints:

I'm having the same issue when I accidentally type Ctrl+\ (instead of Ctrl+/ which does work). Also on ubuntu and the segfault seems to be on the same line as above (../sysdeps/unix/sysv/linux/read.c:26). hstr version I'm using is "3.1.0" (2023-04-18T08:50:00) from the official ubuntu repo.
