Compiling with -O3 triggers the following warning with GCC 8.3:
driver.c: In function ‘dlz_findzonedb’:
driver.c:198:29: warning: ‘%u’ directive output may be truncated writing between 1 and 5 bytes into a region of size between 0 and 99 [-Wformat-truncation=]
snprintf(buffer, size, "%s#%u", addr_buf, port);
^~
driver.c:198:25: note: directive argument in the range [0, 65535]
snprintf(buffer, size, "%s#%u", addr_buf, port);
^~~~~~~
driver.c:198:2: note: ‘snprintf’ output between 3 and 106 bytes into a destination of size 100
snprintf(buffer, size, "%s#%u", addr_buf, port);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Increase the size of the relevant array to prevent this warning from
being triggered.
