            Bug ID: 15211
           Summary: Segmentation fault in ls -l
           Product: Busybox
           Version: 1.35.x
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Standard Compliance
          Assignee: unassigned@busybox.net
          Reporter: ja@sdomi.pl
                CC: busybox-cvs@busybox.net
  Target Milestone: ---

In case of an abnormally high date stored on the fs, busybox's ls -la crashes
on trying to display it. I have experienced this when interfacing with an NTFS3
filesystem which has invalid dates stored in some of the file metadata.

```
(gdb) r -la
