Hi,
Just noticed this on Fedora 28 box (GCC 8.1.1)
=====================================================================
pgbench.c: In function 'ParseScript':
pgbench.c:2640:20: warning: '__builtin___sprintf_chk' may write a terminating
nul past the end of the destination [-Wformat-overflow=]
sprintf(var, "$%d", cmd->argc);
^
In file included from /usr/include/stdio.h:862,
from ../../../src/include/c.h:81,
from ../../../src/include/postgres_fe.h:25,
from pgbench.c:34:
/usr/include/bits/stdio2.h:33:10: note: '__builtin___sprintf_chk' output
between 3 and 13 bytes into a destination of size 12
return __builtin___sprintf_chk (__s, __USE_FORTIFY_LEVEL - 1,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
__bos (__s), __fmt, __va_arg_pack ());
