Bug ID: 51386
           Summary: ln.exe needs KERNEL32.dll.FindFirstFileNameW
           Product: Wine
           Version: 6.12
          Hardware: x86-64

                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32

ln.exe, a command line utility that works with hard links and symbolic links,
can crash during a "deloreon copy" (incremental backup). Specifically, the
command used was this:

ln --backup --unroll --1023safe --progress --delorean <source directory>
<previous backup dir> <new backup dir>

When it crashes, the terminal output says:

wine: Call from 7BC2980A to unimplemented function
KERNEL32.dll.FindFirstFileNameW, aborting

Sometimes the command completes without crashing, so apparently it doesn't
always call this function?

Note: the 32-bit version of ln.exe was used. I haven't tested the 64-bit
version.
