Problem: the server missed the fact that one can read from 2 indexes alternately using HANDLER interface. Fix: check if the same (initialized) index is involved reading next/prev values from the index. mysql-test/r/handler_myisam.result: Fix for bug #54007: assert in ha_myisam::index_next, HANDLER - test result. mysql-test/t/handler_myisam.test: Fix for bug #54007: assert in ha_myisam::index_next, HANDLER - test case. sql/sql_handler.cc: Fix for bug #54007: assert in ha_myisam::index_next, HANDLER - check if we use the same (initialized) index to read next/prev values from the index.
