The code look correct. The compiler gets confused by the `byte[1]`
struct member mapped into a memory buffer with a variable-sized
payload starting at this member. Perhaps there is a cleaner way
to silence this by changing the code.
First seen with gcc 13.2.0 in curl-for-win builds. Then with 13.2.1 and
the latest 14.2.0.
```
curl/lib/smb.c: In function 'smb_connection_state':
