I found a FPE bug and here is the STDERR of smbclient:

```

The cli_pull_send function in clireadwrite.c (https://gitlab.com/samba-team/samba/-/blob/master/source3/libsmb/clireadwrite.c) does not check `state->chunk_size` before dividing it in line 379:

```c
tmp64 = window_size/state->chunk_size;
```
