Bug#20894 Reproducible MySQL client segmentation fault
- Add two null bytes in "buff" variable allowing us to call get_arg two times also for strings longer than sizeof(buff) client/mysql.cc: Make sure there are _two_ zero bytes at the end of buff, to allow 'get_arg' to be called twice on long strings. The first time it will mark end of string with a zero and the second time it will "skip ahead" to the first zero, and the find the second one indicating end of buff. mysql-test/r/mysql.result: Update test results mysql-test/t/mysql.test: Add tests for "com_connect" function in mysql Add test reported in bug
