• snprintf(bufs[0].ft, sizeof(bufs[0].ft), arg);
  

• snprintf(bufs[0].ft, sizeof(bufs[0].ft), "%s", arg);
  

This has been already applied (commit 64692972).

Simply:

strncpy(bufs[0].ft, arg, sizeof(bufs[0].ft)-1);

Though it may not be necessary here, some care is necessary regarding the NUL byte when using strncpy.

Thanks, Ali
