A patch for this bug was pushed (bk commit - 4.1 tree (konstantin:1.1829)) We need to check that client_test works ok on 64-bit Max OS X, which we can't do easily unless we have 64-bit g5 box.

client_test was run on 64-bit Mac OS X The bug does not show up.
Description: Byte ordering is wrong, so the sample below gives wrong output on 64-bit g5s. How to repeat: #include <stdio.h> #include <string.h> #include "common.h" int main(int argc, char *argv[]) { MYSQL_STMT *stmt; MYSQL_BIND bind_array[3]; int id; /* input and output data of 'id' column */ const char *stmt_text; int rc; /* to save return value of API calls */ int i; /* loop counter */ setup_connection(); stmt= mysql_stmt_init(mysql); stmt_text= "INSERT INTO t1 (id) VALUES (?)"; mysql_stmt_prepare(stmt, stmt_text, strlen(stmt_text)); memset(bind_array, 0, sizeof(bind_array)); bind_array[0].buffer_type= MYSQL_TYPE_LONG; bind_array[0].buffer= (char*) &id; mysql_stmt_bind_param(stmt, bind_array); for (id= 1; id <= 3; ++id) mysql_stmt_execute(stmt); st mysql_stmt_prepare(stmt, stmt_text, strlen(stmt_text)); mysql_stmt_execute(stmt); mysql_stmt_bind_result(stmt, bind_array); while ((rc= mysql_stmt_fetch(stmt)) == 0) { printf("fetched row %d\n", id); } mysql_stmt_close(stmt); cleanup(); return 0; } "g5.cc" 50L, 1009Cmt_text= "SELECT id FROM t1";
