Description:
The THD class contains this member
String convert_buffer;                // buffer for charset conversions
which is used as a temporary buffer by THD::convert_string().

This means that THD::convert_string() is not thread safe, which is a problem for multi-threaded execution.

It turns out that THD::convert_buffer and THD::convert_string can relatively easily be removed.

How to repeat:
n/a
