    Description

      I have a rather long SELECT query that retrieves data from multiple tables - a query that crashes when it is executed.

      I've attached the windows minidump. Plus some analysis data from BoundsChecker,

      backtrace:
      1 libmariadb.dll!net_field_length(unsigned char * * packet=0x0018e128)
      *2 libmariadb.dll!mthd_stmt_read_all_rows(st_mysql_stmt * stmt=0x032c7ce8)
      3 libmariadb.dll!mysql_stmt_store_result(st_mysql_stmt * stmt=0x032c7ce8)
      4 qsqlmysql.dll!QMYSQLResult::exec()

      Easily reproducible - please let me know what you need more.
