The reason DKB is hanging during malloc() is because Symbol_Table
is being freed more than once.  Since attempts to free non-allocated 
memory go unnoticed (without side effects) by most compilers, that is 
why the problem is isolated to Turbo C++.

Try deleting the call free(Symbol_Table) in Terminate_Tokenizer.
I am not positive that fixes the problem, but I am sure that the 
multiple free()s are causing it.
