I notice from time to time my $HOME directory has many .core files.
Some of the recent ones being:
adb.core
geany.core
pcmanfm.core
firefox128.core
rofi.core
rofi gdb backtrace:
$ gdb -ex "set pagination off" -ex "bt" -ex "quit" `which rofi`
rofi.core
...
Program terminated with signal SIGSEGV, Segmentation fault.

I run startx from tty to run GUI WM. tty defaults to $HOME, so I assume
this is why they are created there. From my memory I can remember that
some of the programs those files are named of, crashed during use.
I couldn't find any documentation about this, so had to write here.
I have some questions:
1. Why are .core files created?
2. How can I disable creating .core files (without solving the crash)?
Is there any config somewhere, like FreeBSD's kern.coredump sysctl
switch?
3. How can I solve the issue so that there are no more crashes+*.core?
For #3 I have a feeling it might be something relating to limited RAM
given to programs by NetBSD in default setup. I was thinking if
login.conf can solve this? My /etc/login.conf is mostly commented
except I have a rule for tor. In case needed, dmesg on the machine
says:
avail memory = 3736 MB
