I did an extra check of the code but I could not find any reason for
how this could happen.
The above result should be freed by the following code
mysql_free_result():
if (result->fields)
free_root(&result->field_alloc,MYF(0));
Any change you could try to do a trace file that shows your problem?
Just follow the instruction in the MySQL manual in section 'Debugging
a MySQL client'. Note that to debug memory allocations, you should
configure MySQL with --with-debug=full.
