malloc memory not free all

[Former user]

Originally reported on Google Code with ID 383

What steps will reproduce the problem?
1. make a application at windows, just like VC 6.0
2. call testfloatnum.c main() function
3. check the VC output at debug mode
4. find "Detected memory leaks!" in output



What is the expected output? What do you see instead?
free all malloc memory.

What version of the product are you using? On what operating system?
current 

Please provide any additional information below.

I find the problem at the "bc_free_num()" function
as the link free, but not all the ensum part not free all!

thanks !

``` void bc_free_num (bc_num *num) { if (*num == NULL) return;

(*num)->n_refs--; if ((*num)->n_refs == 0) { if ((*num)->n_ptr) free ((*num)->n_ptr);

(*num)->n_next = _bc_Free_list; _bc_Free_list = *num; }

• num = NULL; }

AT: *num = NULL, BUT NOT FREE "free ((*num)->n_ptr);"

```

This refers to the function bc_free_num in number.c which is 3rd party from the GNU

are ref counted, meaning they will be freed only when ref == 0.
