Thanks for the clear report. I just tested this, and noticed that this is happening only with the debug version of the driver and not with the release version, and thats why it wasn't even caught with the regression test suite before the releases. Did you tested this with the release version of the driver ? If yes, what was the outcome. I will investigate and fix why 'my_realloc' is crashing if using the debug version of the MySQL client libraries.
