Using unsupported buffer type: 254 (parameter: 2)

[elekis twoji]

hi all,
I have a little problem with a bind on a pepared statement.

on SELECT COL_1,COL_2 FROM TAB_3, (col_1 et col_2 are defined like char(3)).
I try to get value (with a bind). and so the parameter is MYSQL_TYPE_STRING

but I have the following error

mysql_bind_result() failed :: Using unsupported buffer type: 254 (parameter: 2)

2 thing, this error come with mysql enterprise 5.1 and parameter 1 and 2 are exacly the same. (so why he say nothing on the first ???)

thank you
