An alternative approach. The attached script produces the following

snprintf!

./common/support.c:     fprintf(stderr, "Could not allocate %i bytes for

./common/support.c:  Call gethostname() if supported, else just returns -1.
./common/support.c:  return gethostname(buf, len);

As you can see there is only one (client/gui-mui/gui_main.c)
occurrence of a bad use.
