In the following sscanf calls, '%64s' requires 65 bytes.

splinterdb/tests/functional/ycsb_test.c

Line 584 in 6a2348c

ret = sscanf(buffer, "%c %64s", &result[i].cmd, result[i].key);

splinterdb/tests/functional/ycsb_test.c

Lines 598 to 602 in 6a2348c

	ret = sscanf(buffer,
	"%c %64s %lu\n",
	&result[i].cmd,
	result[i].key,
	&result[i].range_len);

But the length of result[i].key is only 24 bytes.

splinterdb/tests/functional/ycsb_test.c

Lines 244 to 246 in 6a2348c

	typedef struct ycsb_op {
	char cmd;
	char key[YCSB_KEY_SIZE];

splinterdb/tests/functional/ycsb_test.c

Line 17 in 6a2348c

#define YCSB_KEY_SIZE 24

Please either modify the sscanf format specifier, or make YCSB_KEY_SIZE larger.
