            Bug ID: 28797
           Summary: Aborted (core dumped) when `l ,,`
           Product: gdb
           Version: 11.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: wuzy01 at qq dot com
  Target Milestone: ---

I found when I press `list ,,` by mistake (the correct command should be `l=
ist
,N`, and N is a line number), gdb will `Aborted (core dumped)`. So I would
like to create a bug for gdb.

Environment information is as following:

```shell
$ uname -r
5.15.11-arch2-1
$ pacman -Qi gdb|rg Version
Version         : 11.1-4
```

This C file can be a test file.

```c
#include <stdio.h>
int main(int argc, char *argv[])
{
        int a =3D 1;
        int b =3D 2;
        a =3D a + b;
        printf("%s\n");
        return 0;
}
```

```
gcc -g main.c -o main
gdb main
```

Then press `l ,,`. gdb will `Aborted (core dumped)`

Thanks.
