Description:
A minor code review bug, credit to my colleague Yura Sorokin:

static my_bool get_view_structure(char table, char db)
{
MYSQL_RES *table_res;
...
if (mysql_query_with_error_report(mysql, &table_res, query))
...
if (path)
{
if (!(sql_file= open_sql_file_for_table(table, O_WRONLY)))
DBUG_RETURN(1);

Thus, mysql_free_result is not called here.

How to repeat:
Code review

Suggested fix:
For 5.7, call mysql_free_result there.

For lower versions, backport [1], and call mysql_free_result there.

Bug#21246627: ASAN: MEMORY LEAK IN PROCESS_SET_GTID_PURGED()
Bug#21250584: ASAN: MEMORY LEAK IN MYSQLDUMP

Fix three different memory leaks in mysqldump:
1) Remember to call dynstr_free() on DYNAMIC_STRING.
2) Remember to call mysql_free_result() on MYSQL_RES.
3) Remember to call my_free() on string allocated by alloc_query_str().
