[bug-libmatheval] memory leak

[Theran Junck]

Aleksander,

 

You have a memory leak in matheval.c.  Any call to evaluator_create() with an invalid _expression_ will leak 6.6 kb due to the default symbol table not being freed.

 

I changed the error return in evaluator_create() as follows:

 

 

      if (!ok)

    {

        /*@@@THJ: Free the address@hidden Symbol Table */

        symbol_table_destroy(symbol_table);

            return NULL;

    }

 

Best Regards,

-Theran
